Award winning Web 2.0 sites

Seems like is has been a while since I have worked on Library 2.0. I am getting to the end, so I am working on finishing it up. I spend a bit of time bumping around really liked the Imcooked site. It was fun, and I loved to see regular people share their recipes and better yet video so you could see them make the dish. I am not sure how you could use this at the library level. I picture it as more a fun site for personal use. I enjoyed it and saw some good recipes that I would make (if I still cooked).
