As someone who worked for years in commercial print, before most manufacturing moved overseas, I recall the workflows the article discusses as being more automate-able than the author seems to understand. For example, "Making the slightest change became a chore. [1.] Update the 'master' DOCX. [2.] Update the InDesign file ..." --the appropriate way to use an external document as master in InDesign is to use the Place command, which autoupdates text changes as they are made in Word. As another example, InDesign supports multiple formats of EPUB by direct export. I also question the author's familiarity with common LaTeX workflows. "'Why didn’t you just author it in LaTeX? ...' you might ask. [B]ut I prefer writing novels in a word processor, not a text editor." And, "How do I convert an ODT file to TeX?" Word processors offer exports of all kinds, including to plain text, and the purpose of a TeX editor is, like InDesign, to typeset text that is often written elsewhere. Capturing the styling from the word processor seems antithetical to the desire for an advanced typesetting tool.
Overall, as a technical writeup I enjoyed the article; however, I would caution that the author seems to approach publishing from an amateur perspective.
