Book Exchange?

Here's an idea I had for something we could do sometime that might be fun.
I know I have several books around the house that I've read and thought were okay, even good, but I know I'll never read them again. Most of them were bargain books I picked up at Half Price. We could all bring one of those books sometime and do a book exchange. I could think up some fun way to exchange them and we'd end up taking home something new to read. It's just a thought. Maybe not everyone has books like that laying around, but I can think of several I wouldn't mind parting with. I don't mean we should pawn off books that we thought were terrible, unless we think it was just our reaction and someone else may like it.
What do you think?
