You need to checkout librarything.com. It is so cool! It keeps track of the books you are reading and can tell you what other people are reading who have also read the books you have read. You can also add it to your blog so others can see what you are reading as well. It also can recommend other books based on the genre/topics of the books you are reading. One catch, however, is that ten people have to have read the book you have read for it to give you any social data on that book. That can happen quickly, though, last week a book I read had only been read by six people at librarything and a few days later it was up to ten.
