Does anyone here use goodreads.com it's a pretty cool site. I've recently signed up and if anyone is interested in adding another friend you can send the invite to [email protected].

I use their Facebook application. It's a good way to keep track of what you've read, are currently reading, and want to read (and see what books your friends are into).

I love it. I don't mess with these social networking sites, but this one is great. And while a few of my friends use it, I like it more for personal use - just having a log of what I've read and my initial impressions of the book is nice(if I choose to write a review).

I also use it and enjoy keeping up with my out of state friends through the site. We are book nerds so it works out well.

Big fan of Goodreads also use Librarything.
