The biggest advantage for Markdown is that it is in plain text. It looks good in plain text. This makes it incredibly portable, lets me write it in whatever text editor I have at hand (even ssh'd into another machine (though I don't do that very often, everything I write is just in dropbox)). I prefer having my writing sitting on my machine in straight forward plain text formats rather than in HTML. It is so much easier to deal with this way, and it is a one step process to convert it to HTML when I want to post it online. Plus, if I want to convert it to some other format, it would be trivial to do so.
