Here’s a summary of the additions, changes, and corrections that I made in V54; for convenience, you’ll also find that they appear in red in the PDF materials, so you can see what has changed since V52 and V53:

1. On page 70, I added Google Maps to the list of Ajax examples.
2. On page 84, I added Google App Engine to the list of interesting products from Google.

7. On page 132, I added a bullet point with a link to Nicholas Carr’s article on “Is Google Making Us Stupid?“

I probably won’t do any more updates for another week or two, but this should keep you busy for a while. Enjoy…

Here’s a summary of the additions, changes, and corrections that I made in V53; for convenience, you’ll also find that they appear in red in the PDF materials, so you can see what has changed since V52:

15. On page 88, I added a “placeholder” bullet point for the iPhone 2.0 that is scheduled to be announced/released on June 9th; and I also modified a bullet point to reflect my belief that Apple’s distribution of iPhone software apps via iTunes will represent an interesting example of the “long tail” concept.
16. On page 123, which discusses technology trends, I added a note to the bullet point asking whether computers might someday exceed human intelligence — noting that the June 2008 IEEE Spectrum journal has a special report, entitled “The Rapture of the Geeks: separating science from fiction in the technological singularity”
17. On page 127, I added a bullet point indicating that senior executives’ acceptance/non-acceptance of social networks & Web 2.0 will become a more and more significant differentiator; I also included a citation to a recent Wall Street Journal interview with Clay Shirky.
18. On page 130, I added a bullet point with a citation to another paper discussing the use of Web 2.0 in educational environments.
19. On page 134, I added a bullet point with the publishing details of Clay Shirky’s new book, Here Comes Everybody: the power of organizing without organizations.

As usual, you can download the 33-megabyte PDF version of this presentation by clicking here, or on the icon below; you can also download it as a 34-megabyte Powerpoint file by clicking here. It’s published under the GNU Free Documentation license (GFDL), so you’re welcome to modify the material and reuse it any way you want, free of charge; the second page of the presentation provides the usual caveat emptor disclaimers. The material is also available/downloadable as a Powerpoint file from my Slideshare page; but because Google limits the size of uploaded presentations to 10 megabytes (along with several other annoying limitations), it’s no longer available on Google Docs. If you’d like me to make the material available in some other format, or on some other hosting site, please drop me an email note and let me know.

Here’s a summary of the material that I’ve added since the last version

1. On page 5, I updated the count of YouTube downloads of Michael Wesch’s “The Machine is (us)ing Us“; it’s now up to 5.5 million downloads.

Also on page 23: I added a bullet point with a link to a St. Louis newspaper article about using Twitter to provide real-time information about the traffic impact of a repair-shutdown of a busy highway in the area. I added the same information to an existing link on page 100, which discusses the use of Web 2.0 in government.
11. On page 24, I updated the statistics about Twitter to show that it had 1,752,793 subscribers as of May 30, 2008 (which, by the way, represents almost twice as many as the 952,517 subscribers that existed on March 29th); I also added a link to this chart, which shows Twitter’s recent exponential growth. I think Twitter is going mainstream, and will really begin to scale up at this point (if its architecture can handle it, which is very much an open question at this point. If you’re interested in keeping up with the statistics about Twitter’s growth, consult Twitstats whenever you want.
12. Also on page 24: I added a bullet point with a link to GroupTweet.
13. Also on page 24: I added a bullet point link to my blog article about “Twitter in Plain English“.

19. Also on page 25, I added a bullet point with a link to an article about “tweetjects” and “blogjects” (i.e., objects that tweet and blog); and I provided some examples, including the twittering London Tower Bridge, and a twittering house (see also this article from Wired).
20. Also on page 25, I added a bullet point with a link to Tweetclouds, which lets you see which words you use most frequently in your twitter messages.
21. Also on page 25, I added a bullet point with a link to Twitterphone.
22. On (new) page 26, I displayed part of the Zappos Twitter page, as well as a link to a Harvard Business Publishing article entitled “Why Zappos Pays New Employees To Quit — and You Should Too“.
23. On page 28, I eliminated the “private beta” description of Dopplr. It’s now open to the public.
24. Also on page 28: I added a bullet point to indicate that Dopplr is now integrated with LinkedIn, Twitter, Gmail, and Flickr in order to help build a larger network of one’s “fellow travelers”.
25. On pages 29-31, I added more detailed slides to explain what Dopplr is all about.

28. On pages 32-33, I added two new pages of material about special-purpose social-networking sites, and a screen shot of interesting YouTube presentations.
29. On page 46, I added a bullet point with a link to a recent CIO article indicating that enterprise mashups are on the rise.
30. On page 47, I added a bullet point with a link to the “ultimate Yahoo Pipes mashup list“. I also added a bullet point with a link to the Yahoo Pipes Twitter link monitor, which provides a stream of Twitter tweets that contain URL’s.
31. On page 62, I added a bullet point with a link to a mini-wiki tool called Backboard.
32. On page 76, I added a bullet point with a link to an article discussing rumors that Twitter may abandon its use of Ruby on Rails.
33. On page 85, I added a bullet point with a link to an Aprill 30, 2008 Information Week article summarizing Oracle’s plans to build a Web 2.0-friendly version of its enterprise apps.
34. On page 87, which lists several Web 2.0-related things going on at IBM, I added a bullet point with a link to IBM Rocks; and I added a bullet point with a link to a recent article about IBM’s Web 2.0 tools and plans; and I also added a bullet point with a link to a Business Week article about IBM’s use of social networking.
35. On page 88, I added a bullet point with a link to the Wikipedia article summarizing the basics of Microsoft’s Sharepoint product for blogs and wikis.

37. Page 99, with a list of “trends in large companies” got so crowded and busy that I broke it in half, and put the second half on a (new) page 98.
38. On page 103, I added a bullet point with a link to an interesting example of a “laggard” culture: 20% of the U.S. population has never used e-mail.
39. On page 105, I added a bullet point with a link to a Harvard Business School podcast on strategies for succeeding with social networking technologies in the enterprise.
40. On page 126 about ubiquitous/pervasive computing, I added a bullet point with a link to the Proceedings of the 6th International Conference on Pervasive Computing.
41. On page 128, I added a new page about future UI paradigms, suggesting that (based on examples like Tweetwheel, Digg’s UI research, and IBM Rocks) some of them are likely to come from Web 2.0 vendors, startups, and inspired individuals. I also added a bullet point, with a link to Cisco’s recently-announced holographic video-conferencing technology (and I added a link to the Cisco announcement on page 90, which summarizes Cisco’s other Web 2.0 initiatives).
42. On page 99, I added a bullet point with a link to a recent McKinsey survey, summarizing usage of Web 2.0 in businesses.
43. On page 104, I added a bullet point with a link to the transparentgovt website, which has a list of about half a dozen countries whose governments are doing interesting things with Web 2.0
44. On page 126, I added a bullet point with a link to a blog posting indicating that Colombia has recently ordered 65,000 of the $100 OLPC computers, for distribution to its children. I also added a bullet point summarizing plans for a 2010-release of the 2nd-generation OLPC computer, with a link to a press release with more details.
45. Also on page 126: courtesy of Tim O’Reilly, who brought my attention to a May 31, 2008 New York Times article that I skimmed this morning but ignored, I’ve now added a bullet point on the page about ubiquitous computing to the article, which discusses billboards that are connected to the Internet, and which watch consumer reactions as they walk by.
46. On page 135, I deleted a bunch of Web 2.0 conferences that have already taken place, and added a June 25, 2008 event: International Conference on Enterprise 2.0, in Varese, Italy. I also added bullet points for upcoming Web 2.0 conferences such as SuperNova 2008 in San Francisco (June 16-18); Social Networking Conference in San Francisco (Jul 10-11); FOWA in London (Oct 8-10); Web 2.0 Expo in New York City (Sep 16-19); and the Web 2.0 Summit conference in San Francisco (Nov 5-7) . I also updated the details for the Wikimania 2008 conference in beautiful downtown Alexandria, Egypt.
47. On page 136, I added a parenthetical note to indicate that The ClueTrain Manifesto is now ten years old! (which simply demonstrates how easy it is for some companies to ignore major trends for a decade…) I also added a new book to the list: Social Networks Around The World: How is Web 2.0 Changing Your Daily Life?

I also tried to add a visual/graphic image to each page, so you wouldn’t be forced to stare at nothing but a page full of text (actually, I’m not so worried about the impact on people who look at the material on their computer screen; I’m more concerned about audiences falling asleep when I present the material in my seminar). But you should be aware that virtuall every image/graphic that you see is hyperlinked to some non-trivial material — e.g., a Website, an article, a YouTube video, etc. So don’t be fooled by pretty pictures; there’s content behind it.

I’ll probably be making some minor updates to the material during the seminar presentation in Rome next week, so check back from time to time to see if there is a new “V53″ version available.

If you’d like to download the 24.2-megabyte PDF file, which looks much prettier and now has more than 500 embedded URL links to various Web 2.0 books, conferences, articles, blog postings, and other resources, click here.

The same PDF document can be viewed and downloaded from my page on Slideshare; to access that, click here.

Here are the additions, changes, corrections, and refinements that I’ve added to this version:

1. On page 20, I created a new page with some additional information about microblogs that would no longer fit on the old page 19. In particular, I added a sub-bullet item linking to a Dopplr case study published by Stowe Boyd, based on a presentation he gave at Web 2.0 Expo in Berlin in November, 2007.
2. On (new) page 115, I added a new bullet point that links to an article, “The Death of Email,” indicating that the younger generation is abandoning traditional email in favor of IM, Facebook, and Twitter.
3. On (new) page 86, I added a bullet point linking to Tom Davenport’s November 13, 2007 Harvard Business blog about why Facebook won’t succeed in the corporate environment. An opposing viewpoint was posted on the same blog a few days earlier by Forrester Research’s Charlene Li, entitled “Why Your Company Needs To Be on Facebook.”
4. Also on (new) page 86, I added an example on the bullet point about social networking becoming a business tool: in mid-November 2007, the first “enterprise application for Facebook” was announced.
5. Also on (new) page 86, I added a bullet point with a link to a Nov 16, 2007 Computerworld article entitled, “Corporate blogging: does it really work?“
6. On (new) page 112, I added a note about the forthcoming Gumby device, as an example of “ambient devices“.
7. On (new) page 79, I added a bullet point about a “negative” social network called “WeNeither.”
8. On (old) page 19, I added a sub-bullet point indicating that Twitter has even invaded popular television shows — appearing on an episode of CSI New York.
9. On (old) page 13, I added a bullet point for another Web-based service, LiveDocuments, which announced in mid-November 2007. And I provided a link to a commentary on the new service from Nicholas Carr.
10. On (new) page 111, I added a bullet point with a link to a Nov 24, 2007 Wall Street Journal article, “A Little Laptop with Big Ambitions,” describing competitive/political battles that Nicholas Negroponte is having with Intel and Microsoft while trying to promote the One Laptop Per Child On project.
11. On (old) page 10, I added a new bullet point about Kindle to the list of items about how the publishing world is going to be changed by Web 2.0; I reference Steven Levy’s Nov 17, 2007 Newsweek article, “The Future of Reading,” as well as my own recent blog reviews of Kindle, and my recent blog posting that summarizes six other Kindle reviews.
12. On (new) page 28, I added a couple of sub-bullet points to the existing bullet point describing Web 1.0 as “static” content; and I included a link to fleck.com, which lets people annotate and mark up arbitrary web pages.
13. On (new) page 50, I added a sub-bullet point beneath the existing comment about “crowdsourcing,” and provided a link to Google’s crowdsourcing initiative with Google Maps, described as “think globally, mark locally.”

That’s all I’ve got for the moment, though I’m sure more material will emerge in the coming days. Be on the lookout for version 51 in the next week or two…

As usual, the new version is available to you in several different formats. If you’d like to see it as an (ugly Betty) Google Docs presentation, click here. And if you’d like to make additions, corrections, improvements, or enhancements to this collaborative document, please sent me an email (“ed” at “yourdon”-dot-com); there about about a dozen registered collaborators now, though it doesn’t look like anyone has been brave enough to edit the material yet.

If you’d like to download the 22.7-megabyte PDF file, which looks much prettier and now has more than 500 embedded URL links to various Web 2.0 books, conferences, articles, blog postings, and other resources, click here.

The same PDF document can be viewed and downloaded from my page on Slideshare; to access that, click here.

Here are the additions, changes, corrections, and refinements that I’ve added to this version:

1. On page 20 of the material, I corrected a reference to the spring 2007 Virginia Tech massacre. I had incorrectly listed it as “UVA” (i.e., University of Virginia, which ain’t the same school at VA Tech; sorry about that). To compound the problem, the link to Wikipedia was broken. Oh, well …
2. On page 74, I added a sub-bullet noting that Microsoft Windows Live was released from beta on November 6th. Civilization didn’t grind to a halt, but I assume it was significant news to at least a few people …
3. On page 38, I provided an example of the “long tail” recommendation of making at least a portion of one’s product line free — the example being the proposal (in Europe) to provide “free cars.” Sounds crazy until you contemplate this intriguing factoid: he cost of the average used car in Europe is now cheaper than the cost of gasoline to drive it for a year.
4. On page 19, I added a sub-bullet, noting Brady Forest’s blog on the “coincidence feed” feature of Dopplr, announced 11/7/07, and the related concept of REDUCING amount of information in a feed
5. On page 51, I added a sub-bullet point, noting that a “pilot project” to experiment with external wikis doesn’t have to be a massive, high-risk effort. The example is an “emergent collaboration” effort involving SAP, Oracle, and others to develop a Twitter-based tool called “eventtrack.”
6. On page 85, I added a bullet point with a blog summarizing IBM’s experience with social software, and its impact on knowledge management.
7. On page 33, I added the wonderful mashup example of Google Maps’ “interactive transit map” for New York City. But I also deleted the bullet point listing the Google Maps mashup showing the location of the Southern California wildfires in Oct 2007 … because they’re all gone now, and there’s nothing to show.
8. On page 116, I added a sub-bullet point entitled “Web 2.0 Manages to Sober Up“
9. On page 62, I added a bullet point listing Hungry Machine as an example of Ruby on Rails … actually, it’s not an example of a product per se, but rather the name of a company that develops Ruby-on-Rails apps for Facebook.
10. On page 98, I added a bullet point listing a Nov 11, 2007 blog posting describing the recent activity by Nigerian scammers to use Facebook for phishing attacks. The fact that anyone falls for this stuff is mind-boggling, but even if their success rate is only one in a million, Facebook (and Myspace) are big enough now that a few scammers might be able to make a decent living…
11. On page 47, I added some details to indicate that as of Nov 13, 2007, Flickr acquired its 2-billionth photograph. That’s a lot of pictures!
12. On page 114, I added a bullet point with a link to a wonderful Internet love song, entitled “ROFLOMGLOLROFLMFAO“

That’s it for now … I’ll start collecting items for version 50, which will probably take place sometime next week, in between bouts of Thanksgiving turkey-gobbling …

Based on a suggestion from someone attending my Web 2.0 seminar in Rome a couple weeks ago, I’ve also made the “native” mind-map document available; it’s about 21.4 megabytes in size, and you can download it by clicking here. You’re welcome to add, delete, or modify anything you want; but to do that, you’ll need the mind-mapping tool that I used to create the document: it’s called ConceptDraw MindMap, and it’s available for both Windows and Macintosh by clicking here (disclosures: it costs a couple hundred dollars, and I have no business relationship of any kind with the company that makes it). Alternatively, if you’re content to view the mind-map in a read-only format, you can download a free copy of ConceptDraw Viewer (in either WIndows or Mac format) by clicking here. I found the “viewer” program to be extremely slow and clumsy (though it might be speedier when dealing with a small mind-map), but it does give you the ability to expand and collapse the outline-hierarchy of mind-map branches, as well as navigating from page to page. For more straightforward uses of the mind-map, I think the PDF document is probably adequate, but the choice is yours.

The primary change in this version of the mind-map is a reorganization of subordinate topics (or sub-branches) into separate pages; the whole thing had gotten so complex that several of the pages were almost impossible to read, with tiny font-sizes required in order to cram everything onto a single page. As a result, what was previously a 16-page mind-map has now grown to a 32-page mind-map; everything is now simpler, larger, and easier to read. Unfortunately, it has also doubled the size of the PDF document from what it used to be; I hope that won’t be too much of an inconvenience.

I may need to make some additional refinements in future versions; among other things, on the PDF export (and with the ConceptDraw Viewer program) the hyper-linked navigation paths from various branches in high-level pages to the lower-level details on subordinate pages are not visually obvious. This is annoying, because the page-to-page hyperlinks do have a visual annotation in the native ConceptDraw mind-map document; but that won’t be of any use to you unless you decide to invest in a full-blown copy of the ConceptDraw mind-mapping tool itself.

For now, I recommend that you take a look at the names I’ve given to each page in the mind-map, which should help indicate which pages are “high-level” and which ones are “subordinate.” Also, roll your mouse slowly over any terminating branches in a high-level page, and see if a little pop-up message appears that says “go to page n.” If it’s an “external” hyperlink (i.e., a link to something outside the mind-map itself, somewhere on the Internet), the text will have the familiar blue, underlined format; but if it’s an “internal” hyperlink (i.e., to some other page of the mind-map), the text won’t show any special formatting, but when you roll your mouse slowly over the text, the cursor should change from a pointy-arrow to a pointy-finger (at least that’s what it does on my Mac; I don’t know how it behaves on other platforms). Also, remember that all of the subordinate pages are hyper-linked back to their parent-page; all you need to do is click in the central, yellow-colored “topic” bubble in the middle of each such subordinate page.

Meanwhile, here’s a summary of the changes and revisions that I’ve made in this version:

1. Several of the branches that had been highlighted in a red color, for the benefit of people attending my recent Web 2.0 seminar in Rome, have now been changed back to the original black (or blue) text format.
2. On the “Introduction – Society” page, on the branch labeled “Blogs”, I updated a link to a page describing current statistics about the state of the blogosphere — indicating that there are now 71 million blogs, with 175,000 new blogs being added every day.
3. On the “Conferences” branch of the “References” page, I’ve updated the link to last year’s WIkimania 2006 conference, and the link now points to the Web page for Wikimania 2007 in Taiwan.
4. On the “Trends – New UI” page, I’ve added a link to Apple’s web page for the forthcoming iPhone — having looked at it again yesterday while writing my blog posting titled “Waiting for Apple’s Leopard,” I really do think this is one example of a new UI trend.
5. On the “Trends – Social/Cultural” page, I’ve added a new link to the video clip entitled “Shift happens,” which I summarized in this recent blog posting.
6. On the “tools” branch of the “Themes – Mashups” page, I’ve added a link to a MacWorld article by Google’s MyMaps mashup.
7. On the branch labeled “Ed’s list of corporate blogging policies” on the “Business – Large Companies” page, I’ve added a new link to a blog article I wrote a couple months ago, entitled “What A Company’s Blogging Policy Says To Its Employees.”
8. On the branch labeled “Blurring of (some) political boundaries” on the “Trends – Social/Cultural” page, I’ve added a new link to the “Shift Happens” video clip mentioned above, which (among other things) points out that the 106 million registered MySpace users represent a “network nation” that ranks 11th in the world, between Japan and Mexico.
9. On the “References” page, I removed the branch (and link) to the “Dead Web 2.0″ site; it’s no longer functioning, though it promises to come back at some point in the future.

That’s it for now. I may add a few more odds and ends before I head up to Boston on Tuesday, but this should keep you occupied for a while…

I don’t have time to provide a detailed list of the individual changes and additions; however, they are all marked in red text, so they’ll be easy for you to spot.

Enjoy!

Here’s a summary of what I’ve added or modified since the last update:

1. I’ve cleaned up the layout and wording on several of the pages, and rearranged the visual layout of the mind-map to make it a bit less cluttered.
2. On the “Introduction” page, I’ve added a link to the Obama “1984″ mashup YouTube video-clip on the Profound Changes/Society/Political Commentary branch, along with a link to the news article announcing the resignation of the gentleman who created the clip.
3. On the same branch of the “Introduction” page, I’ve added a link to Hilary Clinton’s page on the SecondLife website, as an example of “political commentary.”
4. On the “Trends” page, I’ve added a link to the “One Laptop Per Child” (OLPC) site, as a sub-branch to the Technical/Moore’s Law/$100 laptop branch.
5. Also on the “Trends” page, I’ve added a link to my recent blog posting on the “Sugar” user interface; technically, it’s part of the OLPC project, but I added it to the Technical/New User Interface branch.
6. Also on the “Trends” page, I’ve added a link to Howard Rheingold’s blog posting on “The Next 5 billion Internet Users“; this is part of the “social” branch.
7. Also on the “social” branch of the “Trends” page, I’ve created a new sub-branch titled “Impact on Education.” And I’ve added six sub-sub-branch items there: a link to Columbia University’s Center for New Media Teaching and Learning; a link to an article about the banning of Wikipedia in some universities; a blog posting of mine about the pros and cons to teaching children to search information without access to Google; an interesting blog posting about “crowdsourcing” of reading assignments; another sub-sub-branch reminding people about the use of student wikis; and a blog posting that lists the top web tools for students.
8. Finally, on the “Trends” page, I’ve added a link to an article on “Freebase” to the branch on “Web 3.0″.
9. On the “Technology” page, I’ve added a link to “Yahoo Pipes” to the branch on API’s/Yahoo.
10. On the “Wikis” page, I’ve added a link to Wikipedia’s article on the “Essjay” controversy, on the Risks/credibility of output branch.
11. On the “Products/Vendors” page, I’ve replaced the previous references to “Writely” and “Google Docs, Spreadsheet” with a link to “Google Apps” on the Big Vendors/Google branch
12. Also on the “Products/Vendors” page, I’ve replaced a previous link to the “Top 20 UK Web 2.0 vendors” with a more recent link to the “Top 25 UK Web 2.0 Startups.”
13. Also on the “Products/Vendors” page, I’ve added a link to a blog posting on the “Top 20 Ranked Social Networking Sites,” as a sub-branch of the “Social Networking Services” branch.
14. Also on the “Products/Vendors” page, I’ve added a new sub-branch for “Cisco” on the “Big Vendors” main branch. And as sub-branches of Cisco, I’ve added a link to a recent article describing Cisco’s acquisition of WebEx, and a link describing its acquisition of social-networking vendor Five Across.
15. Also on the “Products/Vendors” page, I’ve added a link to an article describing the 37 Signals HighRise CRM product; this is part of the “Other startups, small vendors” branch.

18. On the “Business” page, I’ve added a link to an article about the risk of malware in Web 2.0 sites; it’s part of the Recommended Strategy/SWOT/Threats branch.
19. Also on the “Business” page, I’ve added a link to a blog posting discussing two recent surveys about corporate reactions to the use of Web 2.0 in business environments in 2007; one of the surveys is quite optimistic, and the other is more pessimistic.
20. Also on the “Business” page, I’ve added two links to the “Developing a Strategy” sub-branch of the “Recommended Strategies” main branch; one of the links discusses the business use of social networks; and the other is a New York Times article titled “Social Networking’s Next Phase.”
21. Finally, on the “Cultural Issues” page, I’ve added a link to an article on the use of Web 2.0 for political commentary by Phillippine activitists, as part of the “People Power/Citizens/Political commentary” branch.

As I’ve mentioned in previous postings, this mind-map was created by simply typing the text and links — along with various graphics and JPEG images — into a mind-mapping tool called ConceptDraw MindMap. The 16-page mind-map was then exported to a PDF file, with all of the hyperlinks preserved. There are lots of other mind-mapping tools available; all you need to do is google the term “mindmap,” and you’ll get an enormous list of articles, tutorials, and “sponsored links” for various tools and products. And if you wonder why on earth I’m using a mindmap presentation, rather than Powerpoint, I invite you to read through my April 25, 2006 blog posting titled “Sayonara Powerpoint“.

There are now approximately 350 links throughout the various pages of this mind-map. But things are changing every day, and I intend to keep monitoring the Web 2.0 landscape. Stay tuned for more updates and additions in the coming weeks…

Here’s a summary of what I’ve added to this version:

1. On the “Conferences” branch of the “References” page of the mind-map, I’ve added a link to the Web 2.0 Expo that’s being scheduled for April 15-18, 2007 in San Francisco.
2. On the “Cultural Issues” page, I changed the wording of one of the branches from “permanent beta” to “perpetual beta,” and included a link to the Wikipedia article about the concept of perpetual beta.
3. On the “Basic Themes” page, I updated a sub-sub-sub-branch entitled “State of the blogosphere” with a link to the latest article on Technorati, which says there are now 57 million blogs. Another link had to be updated, with the same URL, on a sub-sub-sub branch of the “Introduction” page of the mind-map.
4. On the “Trends: 10 Years From Now” page, I added a link to John Markoff’s November 12, 2006 New York Times article entitled “Entrepreneurs See a Web Guided by Common Sense” to a branch called “What’s Next: Web 3.0: mass market -> Long Tail.” There seems to be a growing consensus that a “semantic web” will be the dominant feature of Web 3.0, and I hope to write a blog article in the next few days with my reactions to the NYT article.
5. On the “Trends” page of the mind-map, I added a link to an article entitled “Growing Up Digital: The Rise of the Net Generation” on the “Impact of a new generation of tech-savvy children” sub-branch of the “Social/Cultural branch.” The author, Don Tapscott, has a book with the same title, but it was published in 1999 — before the rise of social-networking sites like MySpace, Friendster, Flickr, etc. Since the article is free, I figured that would be sufficient for most people; but you’re obviously welcome to track down the book, too.
6. The same author, Don Tapscott, has a new book coming out in late December, entitled Wikinomics. He gave a short presentation of its basic themes as last week’s Web 2.0 Summit conference, and it sounded sufficiently interesting that I added a thumbnail image of the book cover, and a link to the Amazon page describing the book. All of this is on the “Wiki phenomenon” page of the mind-map.
7. On the “Products/Vendors” page, I added a new sub-branch to the main branch about “aspects of Web 2.0 usage.” This new sub-branch links to a November 7, 2006 article, “WEB 2.0: Google CEO: Take your data and run,” describing a theme I heard mentioned from two or three of the big-name speakers at the Web 2.0 Summit: if users decide that they’re unhappy with one Internet service/vendor, they should have the opportunity to take all of their data with them (including, in the case of Google, their entire history of previous searches) to the new service/vendor they’ve chosen. At the moment, it’s hard enough to export and import the “obvious” data like calendar entries, address books, and email addresses; but these speakers were acknowledging the fact that more and more of these services (think Amazon, Yahoo, eBay, your friendly Internet “portal,” your social-networking site, etc.) keep an enormous amount of “invisible” data about our history, preferences, and behavior.
8. On the “Long Tail” page of the mind-map, I’ve added a link to the Powerpoint slides from Chris Anderson’s presentation at Pop!Tech 2006, entitled “The Economics of Abundance.” As with most Powerpoint slides, it’s hard to figure out what some of the details are all about if you don’t have access to the speaker’s audio presentation (which, unfortunately, are not available); but there are some great visuals and punchy summaries of what the “long tail” phenomenon is all about. You might also want to read Chris Anderson’s blog posting about his presentation, which I decided not to put into the mind-map.
9. On the “related concepts” branch of the “Basic Themes” page of the mind-map, I’ve added a new sub-branch consisting of a link to Dion Hinchcliffe’s November 5, 2006 ZDNet article entitled “Web 2.0 definition updated and Enterprise 2.0 emerges,” which explains a new mnemonic coined by Harvard Business School professor Andrew McAfee: SLATES. In a nutshell, it stands for Search, Links, Authorship, Extensions, and Signals. Read the article to see what this all means.
10. On the “Recurring Themes” branch of the “Basic Themes” page of the mind-map, I’ve added a new sub-branch to emphasize the recurring theme of empowering individual customers, employees, readers, citizens, etc. It’s a link to an article entitled “Web 2.0: Join the revolution,” in the November 13, 2006 issue of B-to-B magazine.

That’s it for now. More later…
