It’s been a few weeks since I last updated my Web 2.0 mind-map, and there have been some interesting developments, announcements, and new products. I still have several dozen articles, blog postings, and various other tidbits that need to be incorporated into the mind-map, but I’ve added enough new stuff that an update is warranted. As always, you can find the mind-map in the “downloads” section of my website (along with two or three of the older versions), or by simply clicking on this link to download the 8.8- megabyte PDF file.

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.
16. Also on the “Products/Vendors” page, I’ve added a link to an article describing the Zoho CRM product; this is part of the “Other startups, small vendors” branch
17. Also on the “Products/Vendors” page, I’ve added a link to a recent Forrester survey on the types of (big) companies from whom potential customers would prefer to purchase their Web 2.0 tools; this is part of the “Aspects of Web 2.0 usage” 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…
