| May 15, 2017 at 22:21 | comment | added | Yemon Choi | I think this is exactly the kind of question MO was set up for, and I am very dismayed by the votes to close. Or are we just now in the business of saying "let them eat brioche"? | |

| May 13, 2017 at 13:25 | comment | added | YCor | In practice, MO has never been for technically for professional mathematicians. Questions from non-professional mathematicians are welcome when they have are of research level, while too elementary, unclear, or too broad questions of professionals are often closed or migrated too. And many users act anonymously and are not classified so. Thus, I think this sentence is a rough approximation of the target, also in order to discourage people with no relation to research to post highly off-topic questions here, but is certainly not here to select qualified users among others. | |

| May 13, 2017 at 13:01 | comment | added | Bedovlat | This said, I do choose ME when I feel the question must be textbook standard. This time I didn't feel like that for some reason. | |
| May 13, 2017 at 13:00 | comment | added | Bedovlat | By definition, "MathOverflow is a question and answer site for professional mathematicians". I am one, so I feel free to ask questions to my colleagues if I feel it would take me unreasonably long time to find the answer by myself. Note that there is nothing in the definition regarding "asking vs answering" statistics and other religious beliefs. Half of the questions I asked on SE remained unanswered, and many of them are not even viewed sufficiently many times. So I need repost them on MO after losing a few days in vain. | |
| May 13, 2017 at 12:54 | comment | added | YCor | @DerekHolt I'm aware that most questions in MathSE are much more elementary than this. I'm also aware that such a question would have quickly been answered on MathSE. | |
| May 13, 2017 at 12:44 | comment | added | Bedovlat | It is rarely reasonable to ask a question from your narrow specialty, because you probably know it better than others. On the other hand, whatever you ask beyond your specialty is most probably going to be elementary for experts in that subject. Does this mean you should always ask questions only on SE? I don't think so. | |

| May 13, 2017 at 12:37 | comment | added | Derek Holt | @YCor I think you are being too strict here in considering it off-topic. The vast majority of questions on math.stackexchange are much more elementary than this, and so that site is becoming less and less suitable for questions at this level (although it is true that someone would probably have answered it there). | |
