I've seen this happen a couple of times: It's going very fast to put a message on hold, but taking very long (if at all) to revive it.
As with this message, which needed some more seconds of thinking in the original version. Somebody did understand and answer it, but others didn't and voted to put on hold. This is okay, you can expect people to post a better question if they want good answers.
But the problem is, although I reworded the question to be understood more easily, it didn't get enough votes to be reopened. And that's what I observed before. Users struggled hard to improve the quality of their question, but it didn't get rewarded. This is frustrating, as you can see from a couple of questions in meta.
I don't have the 3000 reputation to be part of close voting, but obviously flagged posts draw a lot more attention to get close votes than on hold questions get to be reopened.
What could be done about that?
P.S.: This is not about the given example! That man has his answer and I don't care. Let's not argue about a specific case, but about the general problem.
