How can you resist a name like that?
I'm all about sharing the love so when I discovered BookMooch today (via facebook, where else?) I signed right up. After becoming a member, you enter 10 titles that you are willing to give away to a good home. After listing the titles, search for titles you'd like to come round your place and request a mooch after you earn Mooch points. There is a system set up and a couple of rule/guidelines so people don't get too crazy and build some freakish library with a complete set of troll dolls to act out plot. Wait, that's just me.
