Overwhelmingly, the questions and answers on this site are about learning Japanese.
However, as Tsuyoshi Ito pointed out in some comments on a question I think has no learning value, the FAQ states this site is:
... for students, teachers, and linguists wanting to discuss the finer points of the Japanese language
That definition leaves open room for discussion about things that are not necessarily targetted at people who want to learn or at least improve their Japanese.
I can't deny what the FAQ states, but I have to admit that I find it odd to consider questions without any learning value valid for this site.
There was a question about homosexual symbolism in Japanese literature which seems to have been removed entirely from the site (I can't find it in any searches). I believe it was closed because the only way to seriously discuss it was to have sufficient mastery of Japanese that it carried no learning value to help people get to that point.
Or perhaps it was removed for another reason, but I can't help but think that if simply "discussing" Japanese without learning being a focus, then that question should have been allowed... which I think would be a mistake.
Bottom line, isn't this site really for learning Japanese and not just for arbitrary discussion?
If learning value is not a criteria, then can someone give an example of an acceptable question that is not helpful to Japanese learners?
