I have found this question which relates to the topic, but I wanted to know if someone could (briefly) outline the types of mathematics questions that fall under the Stack Overflow umbrella versus those that should be flagged for migration.
What is meta?
- Any Stack Exchange user can ask a question
- The community provides support, votes on ideas, and reports bugs
- Your voice helps shape the way Stack Exchange operates
Note that if you think a question should be migrated away from SO to a site other than SU, SF, Programmers or Webmasters, you need to flag it for moderator attention (mention the intended destination in the comment, optionally with a very brief and crystal-clear justification).
To provide a few examples, here is the list of questions that have been migrated from Stack Overflow to Mathematics Stack Exchange as of now, according to Google, sorted by decreasing number of votes:
It's not really an exact science... That's why we have humans vote to migrate, rather than computers.
But my rule of thumb would be the ones that include source code belong on Stack Overflow. The rest could probably find a better home elsewhere.
