It seems every StackExchange site is overrun by sophomoric gatekeepers, searching for (& competing with each other?) to find any possible reason to shoot-down questions. It's so much easier to hit that 'downvote' or 'close' button than to actually try to understand the asker, or compose a meaningful answer, or even explain clearly why a question might truly need work. So, I see a lot of 'closes' from people who hardly ever answer any questions, and plenty by people who simply don't understand the question's domain enough to see that yes, that is a meaningful question with a compact, well-matched answer. And once closed, it seems no one really looks at 'reopen' requests, even after the question text improved.
