That's what I use for my personal stuff that I do. I like being able to cut and paste to reprioritise, etc. Also, when planning, having a real editor makes things go so much more smoothly. However, for people who are consumers rather than producers of the plan, I have found considerable friction about removing their drag and drop, table oriented UI. I've often thought about writing a trello-like whose backend was simply markdown or org-mode files that was versioned in a real version control system. There is nothing in the Trello UI that really precludes it (and in fact, there was at one point a program that allowed you to talk to the trello API and grab/push org-mode oriented data from Emacs -- I never found it worked particularly well, though).
