Shelfari

If you love (or like) to read Shelfari is a great website. It lets you keep track of what you have read and what you want to read in the future. I really like it because so often I'll hear about a book and think "I want to read that!" and then I'll forget the book's title within a few days. Now whenever I hear about a book that I'm interested in I just add it to my virtual shelf.
