In one word, YES.
But you aren’t alone either. I feel the same way and use LaTeX for any important writing (and I didn’t start using till after uni either oddly). My resume, a bunch of guides and documents I wrote in it, as well as a book I published. My editor (with WROX) insisted I had to use a Word template for it, but I just couldn’t force myself to. Instead I wrote it in LaTeX and then made a converter to output into their specific crappy template.
(For PC users, there is “the PC is not a typewriter” (https://www.amazon.com/Pc-not-typewriter-Robin-Williams/dp/0...), but that is even older, so I’m not sure it will be more useful than the original, unless your users are using WordPerfect or Ventura Publisher)
Even if people understand that this thing matter, if not matter MORE than his others problems then don't expect much change...
Atlassian Confluence is a horrible recommendation; it has few tools for typesetting, PDF export is very mediocre and hard to control (there is a plugin that allows you to control pagination), and I once found something that was impossible to produce in its markup (my workaround was to insert a zero-width character and hope no one copied it into a terminal).
So my question is, how can I get people to care about this? I've argued for a properly defined corporate style guides as well as adoption of typesetting systems like LaTeX but nobody wants to hear it. Am I just in a minority by being put off by poor typographic and formatting choices and should find more important battles at work? It concerns me that customer facing documentation is severely lacking in quality.
