I voted to close this question, with the justification that it is about mathematical publishing, not mathematics itself, and it would be better suited to academia.SE. This seems consistent with the way we tend to handle questions which are related to mathematics or mathematicians, but which do not actually contain mathematics.
The help-center certainly makes the point that we want questions about mathematics at math.SE, but it doesn't specifically list questions about mathematical publishing as one of the types of off-topic question. So:
Should questions about publishing be considered off-topic, and possibly migrated to academia.SE if they're high quality?
If yes, what should we do about the publishing tag? A glance over the recent questions for this tag suggests that many questions either have mathematical content (and other tags to match it) or have been poorly received.
Similar questions have been considered twice before:
...but at that time academia.SE was still in beta.
