Need a place to bunk?

I posted about my brother's travels earlier and happened across this site today while cleaning out a few flags from a recent magazine ( I use the Post It 1.5 x 2" pads to mark interesting articles to read or URLs I come across that I need to act on later). Couch Surfing should appeal more to his taste and adventures than mine, but thought it was an interesting concept.

According to their website, "CouchSurfing seeks to internationally network people and places, create educational exchanges, raise collective consciousness, spread tolerance, and facilitate cultural understanding." Yeah, like I said - a place to bunk... or meet fellow travelers (online or in person).
