I've been using Org Mode ever since I saw that Literate DevOps presentation... and I'm not even in DevOps at all. It's just that using emacs and Org Mode creates the most usable documentation for recording what I've figured out and done that I've ever seen.
I'm sort of surprised it's not more popular because the productivity gains are pretty damn amazing.
I recently experimented with using org-babel blocks with AWS Athena queries in them (and evaluating them into :result blocks with C-c C-c) instead of putting the queries into my shell history.
The nice thing about this setup is I can keep notes really easily alongside the queries, and the output is right there in the :results blocks. It's kind of like a jupyter / ipython notebook, but for _any command_.
