^Why would you pay for books then give them away? I would go to a public library for free, if I were you, or sell them to a used book store. I've heard of others doing similar things, even of people going so far as throwing books in the trash (!) after reading once. Astonishing.
Personally I prefer mass market paperbacks. I rarely buy hardcover fiction, and I'll only buy trade paper if the publisher won't release a work in any other format.
Since we're just talking about MMPBs and fiction, I see no reason not to give them away.
I just left Foundation and Empire at a bus stop. Though I am in Taipei, so it won't be of much use to many people...also it's a sequel, so it's use to the passerby is close to zero.
