I'm certainly not a Markdown lover. I don't think that taking text conventions from Usenet and writing them down in an ambigous spec is much of an accomplishment. But criticism from someone that thinks that roff is "very simple and [has a] friendly syntax" and has "too little experience with [modern lightweight markup languages like AsciiDoc and reStructuredText]" is probably not that well founded IMHO.
