My main concerns are as follows:
a) we have a dedicated http://mathematica.stackexchange.com stack for them - if they are asked here, they are unlikely to get much attention, they are hard to find and they can't get domain-specific tags,
If your question is not specifically on-topic for Super User, it may be on topic for another Stack Exchange site.
While I get the basic idea that Mathematica is a piece of software, it's also a programming language by itself, a development framework, an IDE etc. - also, I can see no obvious way in which Mathematica is a "super user" tool; for me, it's clearly a developer tool.
and it is not about …
programming and software development,
(side note) is there any place better than https://superuser.com/help/on-topic (meta topic maybe?) in describing what's on-topic and off-topic on SU?
Examples from https://superuser.com/questions/tagged/mathematica?sort=newest&pagesize=50 of what I (my own personal opinion) consider on-topic and off-topic on SU:
on-topic (all of them are concerning very broad scope - configuration, general usage etc):
off-topic (all 3 are IMO programming questions - because they are answered with code):
Of course I consider questions about installing/configuration/platform dependence etc. on-topic here - I just don't think that actual programming usage of a software development platform is. Also, I'm aware that M.SE went RTM ca. 2012 and 2 of the "off-topic" questions are earlier than that date (and that that limits the migration possibilities for old questions also) - yet I'm trying to figure current guidelines; those questions are shown as examples only.
