New Hang-out for book lovers.

I can't believe I haven't found this wonderful internet hideway for booklovers till now-
www.librarything.com
Basically it's an online library catalogue for all your books. You upload all the books you own/ have read and then you can see who has a similar library as your own. It also has handy book suggestions based on the data they've collected from contributors' libraries.
It looks like great fun and I'm going over to explore properly.
I might be gone awhile...
