Fair enough. We can argue about the betterness of org but even if so, its enough better enough to push our something as popular as Markdown. The real item of value is org mode.

Exactly. We should all speak/write Esperanto.

In the meantime, I'll advocate for evolving Markdown, specifically GFM.

I do use a custom keyboard layout, but that doesn't have to interoperate with anything/anyone.

Edit: I have a similar unpopular opinion: we should use functional languages and immutable datastructures. At least we some data of movement in that direction with the patterns being adopted by other languages and codebases.
