Dec 9, 2014 at 19:40 comment added Colin McLarty I thought the point is not at all that the answer should involve novel research, but that the question should arise in research. When MO is called "the best math department in the world" I thought the idea is a researcher might run up against a question not exactly in their field, but needed for their research, and not answerable by normal references, and go ask someone whose field it is. That latter expert might not find the question hard -- only the answer should not be obvious to everyone equipped to understand and use it.
Jul 14, 2013 at 0:25 comment added Todd Trimble I'd agree with quid, and add that it's comparatively rare that answers to "MO-appropriate questions" actually involve novel ideas. Many such questions arise when a mathematician needs to investigate something outside his/her comfort zone, and feels sure that some expert out there would be able to supply the knowledge he/she is missing.

Jun 30, 2013 at 19:48 comment added user9072 In my opinion, in practise, the answer is the level. (Only that on math.SE there is no upper-bound, so in principle there are no questions that are too high-level there, it might just be that one gets better reception on MO, while on MO there is a lower-bound.) Also MO is not for research question, but research-level question, which addmittedly is a vague term, but the FAQs explained it. I'd say advanced graduate-level (5-6+ studies at university) is roughly speaking the appropriateness-level for MO.
