The Couch Surfing Project
Using a FaceBook-like model and a concept that goes beyond â€œyour couch is my couch,â€ the Couch Surfing Project, at couchsurfing.com, encourages members, both guests and hosts, to use their couch time to develop a friendship and share a cultural experiences. It's like a house-swap, but on a smaller scale -- during your stay in the city, you get to sleep on a stranger's couch. In exchange, they'll sleep on yours when they come to your town. The phenomenon is catching on, with over 300,000 members already from over 31,000 places.
