Recently I posted a trivia question using the trivia tag, however, it has now been closed as OT with this comment "I'm closing this question as off-topic because it is not a puzzle; it is simply a trivia question.." after it was learned that it was actually a trivia question as the tag indicates.
The question is current, difficult to guess and, researchable. A bit of fun.
So, my question is, what is the purpose of the trivia tag if it is not for trivia questions?
