Beantal (f/k/a Douban) is a social book site with alot of potential. By this point, beantal is competing with several books organization sites such as whatshouldireadnext and librarything. Beantal's edge is their clean and intuitive interface. After signing-up, it's very easy to browse tagged, rated materials and mark a book as "done it", "reading it", or "want to".
Beantal also includes a music review section. For new music, I'd rather go to Last.fm, pandora, or KEXP, but it's still a unique feature. Maybe they'll include a DVD review section in the future. While we're discussing feature requests, it would be cool if I could print my "want to" list for my next trip to the bookstore.
