I write my blog in markdown and serve it to the browser as such, with a one-liner javascript include to render it in browsers that support that. I like that the "canonical" post source is preserved and served (you can read it with telnet, in a pinch).
had a look and I like it. More "raw markdown" (what the OP uses too) instead of HTML in web publishing is a good thing - basically because xml syntax is not how humans want to write.
This, combined with git forges pages concept or tilde user accounts makes for nice corners in the webs.
Markdown is the least bad way for humans to write, IME. It definitely beats handwriting, it definitely beats every other markup/formatting language, and subjectively I find it nicer than MS Word style "WYSIWYG" formatting although that part is maybe more arguable.
