Sternly looking at you, Nextcloud Markdown Editor.

Disagree.

djot, and several other markup languages, were meant to be read, and evolved from ad-hoc ASCII email formatting that evolved into a defacto standard over a decade.

Markdown was always first and foremost designed to be rendered to HTML. There’s HTML in the spec.

djot, from the author of pandoc, fixes this and a number of other undesirable attributes, and also has a basis in a formal, unambiguous specification. But markdown is so ubiquitous it’s unlikely to be unseated.
