I've been working the First Posts review queue and I am often finding questions that do not provide enough details to permit a helpful answer. (E.g., "Why is cold air coming out of my vents?")
Many times we add comments prompting the OP to add sufficient details, but until they do the question is a waste of anyone's time.
IMO, this is one of the reasons Stack Exchange has an "On Hold" feature. But the two closest canned flags are "too broad" and "unclear what you're asking," neither of which is exactly the problem that occurs so often on DIY. Is there a convention on how (or even whether) questions with insufficient details should be flagged?
