Eh, while Markdown is nice I think Dokuwiki’s syntax is infinitively better for any kind of text that ends up involving programming code. It also has a header syntax that makes sense, albeit rather cumbersome. And it also makes a proper distinction between italics and underline which are two different, standard typographical effects and not the same thing as Markdown seems to believe; and between ordered and unordered lists (let alone nested lists).
Just about the only bad thing is I haven’t been able to find an editor that supports it. Probably because, to my knowledge, no self-standing / independent renderer exists for it (the parser and renderer seem to be tightly integrated into the content manager).
