Thing #11 - Library Thing. Loved it! I uploaded my Harry Potter titles and Gone With the Wind (of course!). I haven't had a ton of time to play with it, but will!
I have a book at home that I keep track of all the books I read. I would like to make a list online of those and then I could catalog the books I actually own - which actually are not that many since I feel like I "own" the millions of books available through SPL and Link+
I think Library Thing is something that I will get a lot of use out of.
