Once you know about pandoc, you orient all of your prose around it, because it's so powerful and useful.
But before you use it, the common opinion is "oh that sounds nice", not "oh let me build all of my workflows around it".
It is incredible how far markdown, sed and pandoc (with filters) can take you!
I've made websites with breadcrumbs, validated inter-document links and images, on and on; mostly pipelines with sed and pandoc.
All of my non-source-code homework in college went through pandoc, and was persisted as markdown source. It makes for clean diffs, and great version history.
Anyway. Give pandoc a try if you haven't already.
