I've used StackExchange sites since day one. Lately not so much so. One reason that I started steering clear was the zealous admins or monitors or other members of the community who vigilantly down-vote, move, or remove on topic questions.
I understand the point of purification; however, during the time I've used these sites it really seems to have gone to the extreme. Often, people have simple questions, which aren't quickly answered by Google or near-by peers and they come to these sites looking for those with more experience in particular topics to help them QUICKLY solve a problem.
And that was my experience the last time I used a stackexchange site, months ago, and again today. Rather than getting a quick answer, I got caught up in the nit-picking process, and immediately I found myself just wanting to leave... and asking when this interrogation and nit-picking is all done, what will we have accomplished? (I'm here for a little hand to a quick solution. Do I have the wrong idea about what these sites should be used for.)
