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 7.1-megabyte PDF by clicking here.

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

1. In the “Examples” branch of the “Wiki phenomenon” page, I’ve added a sub-branch for my own structured analysis wiki; it’s one of a few examples out there of wikis being used to collect updates and revisions to an existing textbook.
2. In the “Apple” sub-branch of “Big Vendors,” on the “Products/Vendors” page of the mind-map, I added a link explaining why Apple’s new web-mail service is so important.
3. On the same “Apple” sub-branch, I added a link discussing a rumor that Apple is planning to integrate (i.e., mash-up) its iPhoto photo-management program (which I love!) with Google Maps.
4. On the “YouTube” sub-branch of “Social Networking Services,” on the “Products/Vendors” page of the mind-map, I added a link to the New York Times announcement of Google’s mind-boggling $1.65 billion acquisition of YouTube.
5. Also on the “Social Networking Services” branch (on the “Products/Vendors” page), I added a link to a SmartMobs blog posting that discusses the interesting trend of middle-age people gravitating to social networking sites like MySpace, Friendster, and Facebook.
6. In the “Examples” sub-branch of the “Wiki Phenomenon” page, I added a link to Wikia’s new project to create semi-private wikis for universities; anyone can read the wiki, but only people with a university-related email address can edit/modify the wiki.
7. On the “Definitions: What is Web 2.0?” branch of the “Introduction: What’s It All About?” page, I added a link to a new Pew Report that discusses several of the current definitions of Web 2.0, as well as their limitations.
8. On the “Recommended strategies for ‘traditional’ companies” branch, on the “Enterprise 2.0″ page, I added a new sub-sub-branch with a link to an interesting blog posting, which suggests that social networking services might be an effective means of bridging the generation gap within organizations, to improve collaboration and communication between the about-to-retire baby-boomers, and the twenty-something workforce.
9. On the “Products/Vendors” page, I added a new link to an interesting site titled “Web Apps Around the World,” which demonstrates that — notwithstanding the recent frenzy of mergers by companies like Google and Yahoo, there really are Web 2.0 vendors and products being developed outside Silicon Valley.
10. On the “Reactions and Trends in Large Companies” branch of the “Enterprise 2.0″ page, I added a new sub-branch that links to the new blog posted by the Director for High Performance Computing at Intel. Yeah, I know it’s not the CEO; but I think it still reinforces the point that reasonably high-level managers in reasonably large companies seem to feel that it’s worth the time and effort to blog about what they’re doing.

That’s all I’ve got time for now. More later…
