I have switched my default entry editor format to Markdown. If you have ever edited a typical wiki, you get the idea. It is great to take notes using a general text editor (or evernote), then copy and paste into this blog and have the entry nice and cleanly formatted. This has been my workflow for my last two posts.
It is probably a quirk of my geekiness, but I find it easier to type in markdown than use a WYSIWYG editor. That's another point for markdown from my POV.
For the curious: Markdown Syntax Documentation
I'd like to learn more ... perhaps a demo? I would love to be able to take notes more quickly and this seems like a good approach. I hate WYSIWYG editors so I usually just set mine to convert line breaks and I use the standard selection of tags ... this slows me down when I am trying to keep up though.
