it is the freaking bomb, yo! there is *nothing* to fill out. screenname and password, that's it. then you just list all of the books you own, creating a virtual library/catalog of all of your favorite tomes. you can use their search engine to find books, or you can do it straight from amazon. you can pick and choose the exact cover that you have on your lovely book. you can review it, rate it, tell people it rocks. they have bits and pieces that will look at your library, compare it to others, and tell you (surprisingly accurately) what other books you might like. they even have an unsuggester, which pretty much tells you which books you *won't* like, so's you can avoid 'em like the plague. PLUS, if there's a book you want, but don't have, they have list people who are looking to trade said book for others. and also, it's just damn awesome. i've been going through like mad. i can do nothing else at work. seriously. it's crazy talk. so anyways, go there and join up so's i can compare my library with yours and see what all i'm missing out on.
(and no, this isn't some ad or anything, i'm just freakishly excited about this ridiculously cool website.)
if you want to look me up, i am ficklevillain, as always. love! and i hope to see you there, yo.
