This is.. about teaching people how to write text documents?
I suppose I was trying to give the perspective of someone doesn't have a problem with authoring a markdown document for example... and bringing myself back to the reality that for most people authoring a document with any sort of formal (rigid, to be interpreted by machine) syntax is unfamiliar.
Now I feel physical pain every time someone sends me documentation in Word format since I know there are at least five diverged versions floating around, with no easy way to compare them (Word diff is stuck in 20th century), full of embedded diagram PNGs that are impossible to update unless you were the author and inconsistent styling on top of that.
