I wonder what the community thinks of adding the option to close a question when the person who posted it did a really sloppy job. With more and more students using math.SE I believe we see an increase in questions that could make perfectly good sense, and that most of us also immediately understand, but that is written in such a sloppy and careless way that it should not warrant any consideration. I would like to have the option to close such questions even if they are not off-topic, not too localized, or otherwise improper except for the presentation.
I think the option is already there, to vote for closure as "not a real question," but I would advise against using it. The usual practice here is to try to coax OP into improving the presentation of the question, even to the point of writing, "I think you mean to ask .... Is that right?"
My feeling is that if OP goes 24 hours without meaningful response to comments aimed at clarifying a poorly presented problem, then it's time to close as NARQ.
