Highlights

•
Markdown makes text readable before parsing
Markdown's fundamental design principle is that the syntax itself should be human-readable—you understand what a `**bold**` or `- list` means without needing a parser to render it.

•
Learning a notation system changes how you think
Once people internalize Markdown syntax, they begin mentally organizing information in Markdown structures—emphasis, lists, links—when writing anywhere, even in contexts that don't support it.

Editorial

•
Apple's mainstream adoption legitimizes Markdown after 20 years
iOS 26's native Markdown support in Apple Notes signals that a format created in 2004 has finally reached sufficient cultural penetration to warrant inclusion in a mass-market OS.
