Assuming this is even close to correct, i am totally amazed!!

That is what I suspect myspace does creating, promoting stories through their own media (fox).

It is not only that the few can only be bothered about supporting each other, but that many of them are so virulent in their attacks on 'outsiders' that the latter often give up posting after a couple of attempts.
