A:I think a cool recent web 2.0 site is Richard Rosenblatt & Lance Armstrong's Livestrong. Hope cool is it that social networking is coming to health and fitness?
Here's Richard Rosenblatts Profile, I think Lance's is in his friends list. Another great Web 2.0 site in my opinion would be www.wikipedia.org. It would show how socializing knowledge / content is just more valuable in a web 2.0 world.
