Since almost all writing is (eventually) done on a computer, is it reasonable to ask technical questions on Writers?
The kinds of things I'm thinking of are: document formatting, automated reformatting, conversion between document file types, document version tracking and management tools, problems with "writer's" software...
There are some other sites that these questions might apply to (for example tex.stackexchange.com if you're using TeX/LaTeX), but the types of problems above are either outside the scope of any particular tool, or highly specific to writers rather than general computer users.
(I'm trying to clarify the scope given the "precedent" on StackOverflow: many questions on SO regarding applications that programmers use could go on SuperUser, but because they're programmer-specific, the in-depth knowledge needed to answer them is more likely to be found in the StackOverflow user base.)
