We've had discussions on the art of couch-surfing, but now Facebook is getting in on the action and allowing users to offer their couches to friends and other travellers and vice versa...except this new application from LA-based TripUp also includes a couch-rating system similar to say, Hotels.com and feedback la Yelp.

Good luck to them--but ratings? If my friends and family didn't give me a 5 every time they wouldn't be invited back :-)
