Wikis the thing..wherein we'll catch the conscience of the patron?

Maybe....this is could be a tool to help us capture what our patrons are thinking about books, movies, music, etc. that we have on our shelves. Bull Run Library had a wiki produced by a patron. Of course this could be something we would have to monitor in some fashion. But it might be nice to get our patrons to put their reviews out there, just like on amazon.com. We could start the ball rolling with our staff picks and then encourage our users to add their thoughts. Just thinking while I'm typing.
