Well, we have a Random Humor forum for posting "jokes, Oddball Images, Funny Links and whatever else". I suggested that it probably belongs there, if at all.
Personally, I think the post is sophomoric but I quite agree that it doesn't appear to violate any rules. There are no rules against hypocracy, simple rudeness, selfishness, stupidity, indifference or a host of other behaviors. It's a good thing there aren't.
More to the point, one consequence of Epic Ski's growth is that many of those who actually knew a lot about skiing and enjoyed sharing that knowledge have left as the number of inane discussions, rude exchanges and rants has grown. You expect a certain amount of that in the off-season but it's' becoming year around now. Not illegal but unhelpful, IMHO.
You are right it is more than just AC's house. It is an internet forum. And as you say, it certainly is about "the audience". However, like attracts like and as the common denominator changes so does the character and quality of the forum. So we can choose to either build or deconstruct this skiing forum or simply walk off the job as many have already done.
