Well, I was going to link the Good Reads website here and see who wants to join me, but the website's nowhere to be found now. Oh well, more on this later. At least I still have Librarything. As soon as I can afford it, I'm getting a lifetime membership. Then you'll see just how big my library is.
I feel like a guy bragging in a bar. Your "library"? Oh yeah. *wink, wink*
EDIT: Looks like Good Reads is back up. I'm not exactly sure how it works yet, but will report back. It sounds pretty cool.
