Calling all couch surfers...

This site (http://www.couchsurfing.org/) was recommended to me by my roommate's friend who was crashing on our couch for a few days this month. Just signed up for an account and am editing my profile. Seems like it might be worthwhile to try and get in touch with fellow travelers, as well as potential hosts in Thailand, Cambodia, Vietnam, and Indo before leaving SF. I do think it would be wise to be cautious and not rely on meeting strangers, but from what friends have told me about their experiences, it's a fairly safe community and holds some accountability. Let the surfing begin!
