I don't ask many questions, well almost never any more, partly because very often when I search I find almost exactly the question I want answered only to find closed as off topic yet it has a half a dozen well reasoned answers and three dozen well reasoned comments.

I think SO and Wikipedia have both suffered the same fate: they started with everyone on the same footing but now there is a core of 'professional' or at least habitual editors who enforce their own narrow view of what is right. I gave up editing Wikibooks after one too many deletes of perfectly valid graphics for nit picking reasons.
