Which is one reason I kind of stayed away from WarmShowers, which at the time (maybe its changed?) that there was not much commenting/rating going on. Hence I have stuck to hospitalityclub which has a much larger user base and not just cyclist orientated and have had pretty good luck with that site. But I think it goes both ways. I use the rating system so I dont get stuck hosting any odd balls and/or staying with any if I do a tour.
