DeScribe

If you don't know about Reddit, it's an online community that reports news events and interesting links as they occur. These get voted up and down by the tens of thousands of users. So it's a hivemind, but it's a pretty good one - I've found out about a lot of cool stuff through Reddit.

Anyways, they also have subReddits for hundreds of different interest groups. One of these is the books.reddit, which, as you might have guessed, is all about books. Go check it out. There's some cool stuff there.
