Certain logical questions belong as well in Philosophy Stack Exchange as they do in Mathematics Stack Exchange. For example this question and this question both fall within the purview of both stackexchanges. But, the people who will read Philosophy Stack Exchange are by no means the same as those who read Mathematics Stack Exchange. Does there exist a way to make it so that questions can appear on both Stack Exchanges? If not, can that get done? If neither of those can get done, how does one communicate the question to both sets of people?
Cross-posting is an issue that has been addressed on stackoverflow:
- cross-posting (having an identical question, either by copy/paste or by an implemented mechanism in the system) is strongly discouraged (and a feature to implement it has been stated will not happen).
- it is not a terrible thing to 're-ask' a question, specifically tailored to each site ("each site is autonomous"), but it is discouraged.
- if your question turns out to just not be appropriate to the site you are posting too or is not getting the expected answers, there is a mechanism to move a question to another site (flag to a moderator and they can 'reassign' the question).
