This question, for example, is currently being reviewed for close. Its chances are good, I think, in that it has already received 2 leave open votes, but there doesn't appear to be any clear-cut reason it was nominated in the first place. Definitely, at least, it doesn't appear that the asker has been alerted to this fact, or that the asker has been given any chance or incentive to edit the question. The same is true of this question.
I don't think we should be in the business of closing bad questions (though I don't consider this question falls into that category, or that they shouldn't be closed as appropriate), but should rather be trying to procure good questions. And so it seems to me that the least that can be done is to alert the asker that their question is currently undergoing review, and to provide them some list of possibly correctable deficiencies.
Am I mistaken somehow, or are these flukes?
