I hope org-mode gets more popular outside of Emacs. I know all the words already about how org-mode is great because of Emacs, but the way you can do plaintext outlining, with great support for TODO's, in org-mode is fantastic. It retains a lot of readability, and that isn't Emacs specific: there are things that make org-mode great as-is!
A small todo application for mobile that uses org-mode as the database doesn't need to parse fancy org-babel stuff, except maybe that org-mode itself can be hard to parse.
Personally I'm hopeful that org-mode gets some more love outside of Emacs, so here's a list of interesting org-mode projects that aren't pandoc or Emacs related:
