I posted a pretty frivolous question on the main site earlier; something along the lines of "How do you fill a blackboard with impressive looking mathematics?"; though I disagree that it was a completely pointless question, I'll agree that math.stackexchange probably isn't the right place for it. Just to clarify:
Is math.stackexchange purely for serious, technical questions, i.e. are questions that aren't directly about learning or doing math inappropriate?
The spirit (but not the letter) of the FAQ seems to imply "yes", but I'm still hoping to get some sort of feedback.
