Personally, I think you have an interesting concept here. As for the other lending sites out there maybe i am daft, but I have been unable to really find any... At least with current books. I would love to find a group to lend my books to as none of my friends or family have readers. I have purchased 12 books since Christmas and they are all lendable ( but noone to share with
). Your question about moderating I would be interested to find out more about it. I am an Internet Marketing Specialist and could possibly be of some assistance on that end...I market real estate professionally though so a bit of a different ball game there.
