I personally use literal plain text for note taking. Previously I used One Note and other stuff, but when I saw how I just store plain text there I grew suspicious that something isn't right and indeed couldn't find a reason why it can't be text files in my text editor. In addition to that my text editor already has best text rendering settings I spent time tuning, and text editing functionality I'm used to - that's the functionality I expect from note taking software. I'm puzzled, how people use markdown? For what? Just to make text more formal?
