So, you're going on a weekend getaway and you don't know where you're staying. You could A) stay on a friend's couch, but you have to take them out to dinner (or do something nice), B) pay for an expensive (yet comfortable) hotel, or C) book a stranger's couch for real cheap.
That's right, now you can pay to stay with a stranger in a strange city. Simply head to AirBed & Breakfast, plug in the city and dates you need a room for, and get a Google mash-up with different faces and prices of who you could stay with. Prices are set by the users, so they range, but most of them are about 15-75 bucks a night.
I know you're all rushing to sign up your very own couch.
