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 à la Yelp.

If you have a Facebook profile, you can add the CouchSwap app and start imposing on all your friends!
