Funny. I am in the process of providing basic training on Markdown to our support staff. I think more than 80% of what we now write is in Markdown format. It is easy to read/write for humans. And AI.
The article pretends that Markdown got popular because “it was there”. 15 years ago people were adopting it _because_ it is dead simple, unobtrusive, and visually evocative.
The ones who made it popular, in other words, did so quite intentionally.
