Here's one answer, by Deyan Ginev: LaTeX is Dead (long live LaTeX): Typesetting in the Digital Age. He focuses quite a bit on output, but touches on content and process as well.

This blog post is cross-hosted on both Authorea and a static web site. For the static hosting, I currently write content in LaTeX and have a smart bit of Ruby create a PDF and an HTML5 blog post out of my “text program”, using XeLaTeX and LaTeXML. I then upload the bundle to GitHub and deploy to my Ruby on Rails site on Digital Ocean. This sounds like, and in fact is, an exercise in programming and juggling technology stacks.
