Please ignore this post. I’m just learning about [MarkDown syntax](http://daringfireball.net/projects/markdown/basics).
* a syntax for writing structured text which is more readable and more writable than straight HTML
* a tool for converting the text into proper HTML on posting
In general, I’d rather store my posts in HTML, I think, but MarkDown seems to be sufficiently widespread (and available as a Perl command-line conversion tool) that I don’t anticipate any problem in getting my data out again if I decide to store it in MarkDown format. Mmmm…
Certainly much easier to write than HTML. And it’s a standard WordPress plugin. You just have to enable it…
Follow-up – I found that the plugin was also used on comments, which confused some people. So I’ve disabled it for now, which is why you can probably see the above as raw markdown source. Fortunately, that’s pretty readable too!
