The moderators recently seem to be hell bent on closing valid questions and answers. Here's two:
Both from my (agreed: subjective) viewpoint are perfectly valid questions and answers, and seem to have high vote counts from interested stack overflow members.
Yet the moderators are closing these based on some (subjective!) opinion of their own.
These seem like the kinds of questions that belong on StackOverflow (or at worst moved to "Programmers") rather than just simply slammed closed.
And of course by deleting (are-all-languages...), most stack overflow members have no chance to see these to vote to re-open.
Over long periods of time, I'd expect some subjective judgement on somebody's part to decide that every question and answer was "wrong", and so the long-term endpoint is "no questions are answered at SO".
