I resisted any involvement with f****k for years, but eventually became a devout convert.
Flying isn't my only hobby, and I make no secret of a strong interest in martial arts. As it happens I just spent half of this weekend having a great time at an Aikido seminar which was largely organised through f*****k with discussions about who was going, where we would train, who was teaching - etc. I can't honestly see much difference between a private f*****k page or website for a small martial arts community and a small flying community. And once it exists, the people know and do stuff together, to hell with it, call it a club.
