Library Thing

I was surprised by how much is available on Library Thing as far as discussions about genres and actual books. It looks like a great place to go for book-related questions and recommendations and to find out which books are currently trendy. I was also surprised by how many varied groups there are and that participants also come from other countries. I also didn't know that the site offers a chance to review an early copy of a book!
The creation of your own "catalog" is surprisingly easy, but I thought they might import more information about the book, such as the publisher. I guess that isn't necessary though, and importing the cover art is a nice touch.
