Kevin from Theory.isthereason, has created a wiki devoted to Web 2.0. He has some great content regarding podcasts, RSS as well as links to some articles discussing the idea behind Web 2.0. What caught my eye at first was a nifty chart comparing Web 1.0 with Web 2.0. It visually helps you understand the difference between the two buzzwords. The wiki is just starting out, but Kevin's been updating furiously so I think this has some great potential. If you think you have any information to add to the wiki, I don't think Kevin would have a problem with you adding to it. Go check it out and let me know what you think.
