I don’t want to go into why couchsurfing sucks, but just point out that there is an alternative, which is free (as in freedom, not as in free beer): www.bewelcome.org.

I’ve still got a CouchSurfing (or crotch surfing as some call it) account, but for my upcoming travels to the States, I’ll try and use BeWelcome only. Here’s my profile on there: www.bewelcome.org/members/dimid.
