I am pleased to announce that this blog supports Markdown. Specifically it’s Markdown Extra, which has a few extra features (like inline HTML support). I’m posting in Markdown via MarsEdit (configuration for MarsEdit is here) using iA Writer for writing the actual text first.
Markdown is enabled in the comments field, too. Try it out!
If you’re a Windows user and you’re interested, I’d like to draw your attention to the excellent WriteMonkey which is just fantastic, even without the extras activated (via donation). There are other Markdown apps on Windows, but this is far and away my preferred Windows editor. It can even jump to different headings (similar to MS Word) and will let you hoist/focus on a piece of text.
