Once again, it’s been a busy week in the Web 2.0 world. I’ve accumulated another bunch of new material, as well as some fixes to broken links and minor editing/rerwording of existing material.

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 22.6-megabyte PDF file, which looks much prettier and has approximately 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.net; to access that, click here.

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

1. On page 1, I provided a link to the Google Docs version of this material, as well as a link to the Slideshare.net version.
2. On page 56, I added a new bullet point to the discussion of Ajax architectural guidelines, based on an observation by Mario Finetti, one of the attendees at my Web 2.0 seminar last week in Rome: Mario pointed out that implementing a Web application in Ajax often requires a large cultural adjustment by many programmers, who were previously advised to avoid client-side processing in a Web-based app, and to do as much processing as possible on the server. Ajax-based apps, by contrast, involve a large amount of Javascript processing in the user’s client browser.
3. On page 19, I added a sub-bullet point about Twitter, from a Nov 4, 2007 New York Times article entitled “The Global Sympathetic Audience,” in which Twitter-based interactions were characterized as “ambient intimacy.”
4. On page 85, I added a reference to Luis Suarez’s Oct 29, 2007 article on “Ten Reasons CEOs Should Blog.”
5. Also on page 85, I added a reference to a June 2006 Scobleizer blog, confirming the bullet point indicating the roughly 3,000 Microsofties blog.
6. Also on page 85, I added a link to a blog article entitled “Web 2.0 Gets Business Chops,” indicating that more than 50% of respondents to a recent IT management survey felt that Web 2.0 is an overhyped buzzword. And I added a new page (page 87) that displays the results of that survey as a bar chart.
7. On (new) page 115, I added a reference to an article entitled “Wikipedia Becomes a Class Assignment,” as part of a list of topics about the impact of Web 2.0 on education.
8. On (new) page 113, I provided a link to the Slideshare.net version of “Shift Happens,” in addition to the existing link to the YouTube video version.
9. Also on (new) page 113, I added a link to a November 2, 2007 New York Times article entitled “Devices Enforce Silence of Cellphones, Illegally” as a sub-bullet to an existing bullet item entitled “revenge by gadget“. And I added a second sub-bullet with a link to PhoneJammer, as an example of such a “revenge” device; I don’t have one (yet), but I think it’s a terrific idea!
10. Finally, on page 65, I added several links and sub-bullet points related to the recent announcement of the OpenSocial API for social networks. In addition a “generic” news announcement from Yahoo News, I also included: a link to Google’s announcement of the consortium effort; Nicholas Carr’s comments on OpenSocial; Dan Dodge’s blog posting on “50 million Facebook users don’t care about OpenSocial“; a perspective from Nicole Ferraro (editor at large, at Internet Evolution); John Battelle’s comments on MySpace joining in with Google; an O’Reilly commentary; Stowe Boyd’s comments and perspective; and a summary/opinion about OpenSocial from Marc Andreesen (co-founder of Netscape, and CEO of Ning). If that’s enough to keep you busy for a while, then you’ll have to start doing your own damn research!

That’s it for now; I actually hope things will slow down for a little while, so I can catch up with the rest of my life. Meanwhile, though, happy reading…
