Should there be more than one sort of math community?
There are, to my mind, two very different but important kinds of mathematical question. There is the kind that the Codidact and SE communities both like: Straight-forward "give the proof/calculation" questions. This can be "How do I solve this?" or "Why is this wrong?" or a few other variations.
But there are "soft" math questions that are not about the math itself but about the philosophy of math ("Is math invented or discovered?"), or the psychology of math ("When I see a problem like this, what methods or theorems should I think of to solve it?"), or for book recommendations, and so on. Of course the Codidact and SE communities both strongly discourage these questions. It's understandable in that they are often harder to answer.
BUT that doesn't mean that they are bad questions, or that one shouldn't ask them, or that there aren't good answers, or that a community shouldn't exist to help with them.
I can see reasons why maybe Codidact might not want to take on the challenge of hosting a community for these kinds of questions. It will probably have a low answer-acceptance rate; it will probably be prone to debate and therefore difficult to moderate; Codidact is small and other features are probably higher-priority to implement, I suppose.
So I understand if we ultimately don't want to have such a community. But I just wanted to bring up the possibility and see what people's thoughts are.
