I wouldn't say the rules regarding notability and verifiability are too harsh as such. They are fine. It's more that, like everything else on Wikipedia, they are applied so unevenly and open to so much abuse.
SandyGeorgia, who commandeered and distorted the Autism articles, just to show she could, has also managed to take over and dominate the "Manual of Style" and the "Featured Article" process. In any article she and her cronies turn their attention to verifiability, notability and "encyclopedic style" are decided solely on their personal whims, with material of equal, or greater weight being discarded often simply because the editor submitting it does not also "submit" to their control game.
To me, this is quality of content being dictated by, and sacrificed to, an increasingly dysfunctional group dynamic.
I very much doubt if SandyGeorgia and her cronies are the ONLY faction playing these games at the expense of content. IF a way could be found to stop these "power games" coming into play, and being pandered to at the expense of reality, all the way up to arbcom level, Wikipedia would be a remarkable project indeed.
But as it stands, though originally intended to operate impartially, impersonally and transparently, more and more of Wikipedia is being defined and decided in accord with a "pack order", unworthy of stray dogs, that works itself out by private email and IRC among a select few. Ironically, a lot of the *formal* opposition to Wikipedia consists largely in failed aspects of exactly the same dynamic.
I suppose it's just another example of something that should have been remarkable (and was, at first, for a while) ruined by the frailties of human nature ramping up to overdrive.
