(This question does not apply to questions where the question-asker asks and answers their own question, that's clearly OK and even encouraged)
There have been some questions, for example
What was the first piece of wood to reach the far side of the Moon? Or the first spacecraft?
Have any knots been tied incorrectly on a spacecraft?
where it's pretty clear the question-asker knows the answer but chooses not to post it right away.
They end up being ok because answered by the asker, but in the interim, they attract downvotes.
Given that this kind of question is a legitimate question, could tagging such questions with a tag-specified-for-these-kinds-of-questions prevent the reflexive downvoting that has been seen?
It seems to me that if it's acknowledged from the git-go that the question is a quizbowl type question, people might not be annoyed. Of course there are always drive-by downvoters.
