We recently migrated a question about FrameMaker to SuperUser. I'm learning the ropes here, so I interpreted this as meaning software questions belong in SuperUser. Yesterday, I suggested migrating a question about Scrivener to SuperUser, but @Neil Fein responded that it is on-topic in Writers because it's a specialty writing tool. By that reasoning, FrameMaker questions belong here, too. I'm sure this question has and will come up for other writing-focused tools. Any thoughts on how we can come up with a broad guideline for this situation that treats different types of writers and software (creative vs. technical) equitably?
TL;DR - Let's keep Scrivener on-topic and explcitly make Framemaker on-topic, with caveats.
What's the situation now?
Here's the situation as I understand it. None of this is set in stone and we as a community can discuss this and change it if we like.
While the program is on-topic at Superuser, there are not many Scrivener users there... but there are many of them here: At this point in time, we have a Scrivener tag and a body of questions on the program. (The same logic should apply to the screenwriting program Final Draft and any other writer-specific tools, including Framemaker and other technical writing tools.)
All of these programs are also on-topic at Superuser or other sites. Using indesign add an example, the program isn't only a writer-specific tool, it's also used by graphic designers. Migrating such a question to Superuser makes sense (or possibly to the Graphic design site, although we'd have to check that) as it'd get more and better answers.
The Framemaker question you link above is specifically about formatting and isn't really a question about writing or a related field, more about the appearance of a document. But it's clearly a question about a writing tool. It'd be fine here or on superuser.
This sort of potential dual on-topic-ness isn't all that different from questions that could be on this site and on English Language and Usage, or her and on Academia, etc. But it's worth noting that no other site really handles Scrivener well. That's not the case with, say, Microsoft word, or other tools that do things other than cater to writers and writing.
So what should we do?
It makes sense to continue keeping Scrivener on-topic here and explicitly make Framemaker on-topic, assuming they're about the writing aspects of these tools.
When it comes to tools like MS Word and InDesign, I'm fine with having questions on more than one site. The cross-posted question should add value to both sites and, ideally, be slightly different for each site. But this isn't a common situation.
I suggest that in the future, we migrate these questions to Superuser/Graphic Design/Wherever but, in the case of questions that could also apply here (such as questions about how writers interface with Framemaker, or how tech writers can use the techie features of MS Word, etc) we make an effort to keep those questions here or encourage variations on multiple sites.
