Questions (it seems) attract negative votes *less* on the basis of the question (that it isn't a philosopher's question, unclear what the question is) than what is involved in answering it (answers that aren't philosophy, unclear how to answer). I claim this because I can provide a ***vast*** quantity of clearly expressed questions about philosophy (especially by me, less by others as I read few downvoted questions) that are closed for being off-topic or unclear. So point proven then, unless the voting patterns for me are normal. One has to get used to that feature of the site. In this instance, you could end up getting such a cluster of different answers that it misses the remit of the site, which is not thinking philosophically, but a Q and A thing. So it's too broad, even if that wouldn't end up degenerating into opinion or incoherence.
