@benwerd I use markdown for initial authoring purely for speed, esp. when typing on mobile devices. After that I just edit the HTML. I’ve yet to come across a WYSIWIM editor which satisfied my semantic, well-structured HTML needs, any suggestions?
I don't get why you'd use markdown to blog on your own site. Markdown is useful: an easy-to-use notation system that allows you to mark up your text in a safe, fast way.
