Posting on a bulletin board such as A2K and spouting opinions is much like driving down the highway and giving the finger to the stranger in the other car who cut you off. We are all anonymous and know that we can say whatever outrageous thing we want to the other guy/gal (within limits set by the moderators) without getting punched in the nose.
Here, posters can be whomever they portray themselves to be. While I've only been on A2K for a short time, I've seen statements made by some posters and I can't believe they honestly mean some of the outrageous things they say.
Is there a hierarchy here? I don't know. I haven't been here long enough to give an educated opinion about that. I can say, however, that the last bulletin board I posted on, definately had a hierarchy and an inpenetratible clique.
I'm not sure where I fit in yet. I might need to use a shoe horn.
