It’s been a while since I last updated my Web 2.0 mind-map. I’ve been steadily acquiring links to interesting articles, analyses, guidelines, and other resources, and have now incorporated them into version 20 of the mind-map. You can find it in the “downloads” section of my main web site at www.yourdon.com/downloads, or you can simply download the 7-megabyte PDF by clicking here.

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

1. Ian Delaney, at TwoPointTouch, composed a very thoughtful blog posting about the limitations of today’s popular definitions of Web 2.0. I added it to the “definitions” branch on the “Introduction: What’s It All About?” page of the mind-map.
2. A couple weeks ago, TechCrunch posted an article about a startup called Dapper, which claims to provide an API service to extract data from any website. I added a link to the TechCrunch article to the “API” branch of the “Technology” page of the mind-map.
3. I decided that instead of a mind-map page labeled “Business Issues,” the phrase “Enterprise Web 2.0″ was a more appropriate and descriptive. So I changed it. Big deal.
4. TechCrunch also provided a heads-up alert about a new blog called WebWorkerDaily, which caters to the lifestyle of today’s Web 2.0-enhanced distributed worker. I added a link to the TechCrunch article to the “Reactions and Trends within large companies” branch of the “Business Issues” page of the mind-map. And, as if I don’t already have enough to read each morning, I added WebWorkerDaily to the list of RSS feeds in my NetNewsWire aggregator.
5. Ian Delaney, of TwoPointTouch, did an interesting interview with Digg’s founder, Kevin Rose; I added a link to his interview in the “Digg” sub-branch, of the “Other startups, small vendors” branch of the “Products/Vendors” page of the mind-map. Just for the heck of it, I also added a link to the blog posting that I wrote about Digg after visiting them in late August 2006.
6. In turn, that reminded me that I should add a link to my blog posting about JotSpot to the appropriate sub-branch of the “Tools” branch on the “Wiki phenomenon” page of the mind-map. But of course, as a faithful reader of my blog, you’ve already read that report, right? Right?
7. While thinking about Wikis, I remembered that David Weinberger (author of Small Pieces, Loosely Joined, co-author of The Cluetrain Manifesto, and an all-’round charming, interesting guy and prolific blogger) had recently written an interesting blog posting about the credibility of Wikipedia. So I added a link to his post to the “credibility of outputs” sub-branch of the “risks” branch of the “Wiki phenomenon” page of the mind-map.
8. I found an interesting article entitled “Why CEOs Are Afraid of Social Media” in the Enterprise Web 2.0 blog (which, I must admit, I had not seen before. Sigh … yet another one to follow in NetNewsWire), and I added it to the “Reactions and trends within large companies” branch of the “Enterprise Web 2.0″ page of the mind-map.
9. Ian Delaney, that handsome, hard-working, debonnaire Web 2.0 wizard from the other side of the pond, posted a blog entry entitled “Should Papers Be More Like Blogs?,” which in turn pointed me to an August 1, 2006 blog posting entitled “The Use of the Internet by America’s Newspapers,” in something called The Bivings Report (which I had never heard of before). Ian added some analysis and commentary of his own, but I’m afraid that if I heap too much praise on him, he’ll feel he’s entitled to a Knighthood or whatever other obscure honors the Queen still doles out in her spare time … so I just added a link to the Bivings Report article to the “publishing” sub-branch that’s buried at the end of the “Web 2.0: profound business, social, technical changes” branch on the “Introduction: What’s It All About?” page of the mind-map.
10. Tara Hunt wrote an interesting blog posting entitled “Speculative Success and YouTube,” which pointed me to an August 10, 2006 article by noted industry pundit/gadfly John Dvorak on the reasons for YouTube’s success, entitled “Missing the Point About YouTube.” Bottom line: if you find a product/service that satisfies a pent-up demand (e.g., uploading a video clip that’s sitting on your computer but really ought to be somewhere on the Internet, for everyone to admire), and if you make it incredibly easy to use (e.g., like a Mac), you’ll be rewarded with fame and fortune … or something like that. Anyway, I thought it was a good insight, so I added a link to it, as part of the “YouTube” sub-branch, in the “Social Networking Services” branch of the “Products/Vendors” page of the mind-map.
11. I added a link to my recent blog posting, “What Does Generation Y Want?” to the “Impact of a New Generation of Tech-Savvy Users” sub-branch, on the “Social/Cultural” branch of the “Trends: 10 Years From Now?” page of the mind-map.
12. I added a new branch to the “Basic Themes” page, entitled “Recurring Themes.” It consists of a link to a blog entry that I wrote after visiting half a dozen Web 2.0 vendors in late August 2006, entitled “Recurring Themes from my Web 2.0 Visits.“
13. I added a new sub-sub-branch to the “Google” sub-branch on the “Products/Vendors” page. It consists of a link to the blog entry that I wrote after visiting Google, entitled, “My visit to Google: Maps, Maps, Maps.”

There’s plenty more to add, including another 20 Web 2.0-related URLs that I’ve already skimmed and marked for incorporating into the mind-map, plus 84 … whoops, now it’s up to 86 … new blog entries that NetNewsWire has picked up while I’ve been blathering away about these 13 new items. But they’ll just have to wait until I have a chance to start working on version 21 of the mind-map. At least this stuff keeps me off the street, and out of trouble…
