A network of couches and houses open to travelers.
When you surf a couch, you are a guest at someone's house. They will provide you with some sort of accommodation, a penthouse apartment or maybe a back yard to pitch your tent in. Stays can be as short as a cup of coffee, one night or a few months. When you offer your couch, you have complete control of who visits.
A "vouching" system signifies an elevated level of trust in the community. I wonder when they will add a roster of "longest surfers"...
