There seems to be a never-ending supply of new exchanges cropping up... however many of them have crossed into the realm of speculation and opinion, not fact based and absolute (like the original exchanges were intended as authoritative).
Are these allowed, and why? Some of the exchanges even seem to be redundant of one another, such as Mathematics Educator --> Academia or Mathematics. Will there eventually be a ____ Educator exchange for each type of subject? Workplace exchange in particular seems to be entirely opinion based as most questions involve "how to handle situation X" (the only thing I can see as factual in the Workplace exchange would be questions about labor laws, etc... but then this would cross over into legal advice)
