Please reprimand me if it's against etiquette that I'm using a particular question as a peg: This question was asked in good faith, but when I see the present state of it, then it seems that the OP might have lost interest in it. Martin Scharrer has asked him to post an answer, which is good, and it's also good to wait a bit so that the OP can do that.
My question: Would it be good to vote to close such questions as "not a real question"? As I said, it shouldn't be closed immediately, but from time to time we have questions of a similar type that stay open without answers, and I think "not a real question" is a close reason that makes kind of sense here. What do you think?
(A close reason I'm somewhat missing in this connection is "OP failed to provide details". But I won't make that a feature-request; I expect the answer would be 'chose "not a real question" instead'.)
UPDATE: If we follow the time frame "~ month" from Joseph's comment to Martin's answer, then another question pops up: What could be the means to really do close some questions after more than a month? The "Unanswered Questions" list helps, but how could we gather 5 close votes then?
