site I listed a few of my books on yesterday. I know they have a similar nook site already. I've borrowed one book and loaned out two already.

Not many of my books in my archives seem to have it turned on and many of those that do were freebies anyway. I would especially be much more willing to shell out $12.99 for a title if I knew I could lend it at least once.... like for instance, Jayne Krentz's In Too Deep which was released this week and I haven't bought.
But maybe Lending will develop into something decent over time if and when the Publishers ever get the heads out of their asses.
