If the forums of Audiogon are any indication of the type of people that use Audiogon, I would stay away. It is really a case of the inmates running the asylum. If you are of the "my ears never lie" crowd, you are free to insult, harass, dog-pile, and defame those that disagree with you. It is especially popular with the old-timers. However, try to use a little common sense, or to call out blatant shilling, and see your posts removed and your account cancelled.
It is the audio equivalent of a far-right, anti-science, conspiracy theory site. Totally crazy.
Someone recently tried to have a discussion on rap music. After the overt racist posts, and arguments, which did not go the way of the old timers, the threads (3 now I think) were cancelled by Audiogon. Can't be having a thread where the old timers hang themselves out to dry!
Things are likely okay for them now as wealth grows in the world, but with their very old average age of user, almost exclusively male, but the younger crowd won't put up with the selective censorship, anti-science stance, and just out and out douchery.
Oh, and those threats someone else alluded to? Not a joke unfortunately.
