I've had great experiences from couchsurfing. Hosting, surfing, and events. I've met several close friends through couchsurfing. I've heard about the negative experiences people have had, but never from direct source, always someone heard about someone. I have no clue about the actual numbers. The community died off with the mismanagement, but also shrunk from the rise of airbnb and meetup.
