Looks nice but isn't the point of markdown pretty much that you can still do your typing in clear, explicit plaintext and then merely generate properly formatted html/pdf/whatnot from it, effectively avoiding any wysiwyg editing?
That's what different mark-up languages such as SGML (HTML/XML), LaTeX, even Org mode, etc generally try to achieve: to separate content and presentation. That is, to write the meat of the text explicitly and not even able to worry about how it will look.
