How soon should I “vote to close”?
Given a question that is not clear at first, which satisfies the criterion for being "not a real question":
"It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form."
should that question be closed immediately, or should the OP get a chance to improve the quality of his question.
My modus operandi is this:
When I encounter a question which is "not a real question", I respond via a comment - I might ask one or more counter-questions (about the issue), I might comment that I don't understand the question. So, I let the OP know that his question should be improved. I then give the OP say 15 minutes to respond (and in most cases the OP does respond). However, if the OP doesn't respond, then I consider voting for "not a real question".
Is this how SO should work?
I have witnessed in the past several questions for which I saw potential, being closed immediately, and I wonder if that is appropriate.
Edit: Of course, questions that are duplicates should be closed immediately, and off-topic questions should also be moved / closed immediately. In this question I am specifically referring to those questions which "have potential" (which could be corrected / improved)..
