As someone who has been a member at
Books For Nooks for about half a year (and I think it's been in operating since about the time the Nook was released), I'm not sure why several people here keep coming up with a "I think I should create yet another book lending site" just because they think they can write a nicer interface. One of the issues is that these sites need a critical mass. Most people will probably pick a single site , and if they don't see something they want to borrow at that site, they'll just give up. Who wants to enter 50 books at multiple sites and keep the status updated at the rest after loaning from a request at one site?
