What are people's feelings about questions which are about education or pedagogy, but not specific to mathematics? An example I have in mind is this question, which could apply equally well to any field in which factual questions are asked.
Personally I'm inclined to be as inclusive as possible — at least as long as the site doesn't become so full of general-pedagogy questions that it loses interest for people interested in math pedagogy, which seems like a very unlikely scenario anyway.
