Occasionally I see questions on math.SE where either the answer is completely trivial -- for example this one where the correct answer would just be "Yes. You did it correctly" -- or questions where a few questions/responses from people in the comments is enough to answer the question for the OP. Either way an answer just seems to be overkill.
What is the policy with these types of questions?
My $\$0.02$: I can't see most of the questions of these types being helpful to anyone, thus I would think that they should be closed. But none of the closure reasons seem to fit. Perhaps we could make a new one?
