> What do you mean "non-emacs users have a tough time contributing to documents"? If I use org-mode files for anything more than markup such as org-babel, ditaa, properties, spreadsheets, scheduling, etc it requires all of the org-mode baggage that only exists in emacs but is what makes org-mode more useful than markdown. But even some of the more advanced org-mode features have to be manually managed if you're trying to contribute to an org-document project and are using something other than Emacs.
