I mean that notes (at least for me) tend to be short. What I don't like is that many note taking systems think that a note needs to be edited like e.g. an Email or Word document (the Evernote approach). So when I see e.g. 10 notes I want to see the most of the content of the 10 notes very good and when I go into one note I don't want to see a whole big word processor with one blank sheet. Google Keep is doing a good job there, also not bad is e.g. Tiddlywiki.

Simplenote gives you the ability to take notes in markdown and be able to view the rendered version by swiping right.
