Questions (it seems) are closed *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).

One has to get used to that.

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.
