I just tweeted on this, as I think it is a great concept. Check out bookmooch.com if you are not familiar with the idea. Basically just a way to trade books. It would be nice to see more atheism-related titles there (the trouble is I tend to not want to give away *those* books)
Haha, I wouldn't either. We have a used bookstore in my area and we have one little cubby hole for the section atheism : / and I am glad when someone sells those books to the store for others to buy, I just can't bring myself to sell them back or trade when I am done reading them. I didn't think twice about getting rid of my christian books ; )
