Sites on the Web 2.0 Awards list

I was just beginning to think there weren't many sites that were really useful to me beyond some the I had already looked at earlier in this process, when I found BeGreen. I found it a little rigid to use, but its "heart" is in the right place. The only problem I had was that aside from driving a car too much (so I can listen to all those audiobooks) I already do all those things. Then I found Farecast which seemed a really good idea, but having just had BeGreen discourage air travel I was torn about when I would use it. I will go back and see what else I can find....
