Real answer, though not who you were replying to: Org mode syntax is more appealing to me, particularly the wiki-style links. I liked it enough to use it before I used Emacs with vim-org but it was lacking so I'm happy enough editing with either Emacs on the desktop, in the browser (Github Wiki), or in Editorial (iPhone). Editorial actually does collapse/expand for Markdown so it would be nice to have that for .org files too, but I would put up with a lot of crap as long as I can work with my files in Emacs 10% of the time.
