classroom link web 2.0 tools

http://www.classroom20.com/ is a link i found that shows a classroom that uses 2.0 tools, and it showed how the transition is completely different from in the classroom and the online classroom. I do not find that hard to believe. I think some of this seems way too much, especially with social networking the classroom, i think some information should be kept private. If the blogs were strictly educational i would agree more with it, but personal information shouldn't be given or shown through these classroom blogs.
