I don't know much about the competitor sites so am asking out of interest as opposed to any professed insight (although I did buy my wife a kndle for Chrsitmas). It seems a smart approach (if it's not being done already) would be to pick a specific niche and become the 'kindle lending site of X'. That way you can get a reputation for having the most books about X available to lend at any moment. What that would ne I don't know. Or maybe look into book clubs, a lot of book clubs must read the same books a lot of the time, maybe seeding with a few copies of books from some celeb endorsed list could kick start a book club lending site?
