LibraryThing

This is actually a pretty nice site that, among other things, gives you book recommendations based on the books you've added to the site that you've already read. Since it was early in the morning when I was surfing the site, I simply added the last 5 books that I've read to the site.

Here's the link to my profile page on the site with my 5 books: http://www.librarything.com/home/Maverick4527
