I write everything in Markdown now. These link posts start in Obsidian, which stores them as .md files. When I rebuilt my blog with Astro, I moved from a database to plain Markdown files. It felt like going backwards—and also exactly right.

Anil Dash has written a lovely history of how John Gruber’s simple text format quietly became the infrastructure of the modern internet:

The trillion-dollar AI industry’s system for controlling their most advanced platforms is a plain text format one guy made up for his blog and then bounced off of a 17-year-old kid [Aaron Swartz] before sharing it with the world for free.

The format was released in 2004, the same year blogs went mainstream. Twenty years later, it’s everywhere—Google Docs, GitHub, Slack, Apple Notes, and every AI prompt you’ve ever written.

Dash’s larger point is about how the internet actually gets built:

Smart people think of good things that are crazy enough that they just might work, and then they give them away, over and over, until they slowly take over the world and make things better for everyone.
