Why Markdown Became the Default Way to Write for the Web

Readable even before it's converted

Markdown, created by John Gruber in 2004, was designed around one core idea: formatted plain text should already look like what it means, even before any conversion happens. A line starting with # visually stands out as a heading; text wrapped in **asterisks** reads as emphasized even in raw form. Raw HTML doesn't have that property — a heading written as <h1> tags is legible, but it's cluttered with markup that gets in the way of just reading the text.

Low friction beats full power

Markdown deliberately covers only a small set of common formatting needs — headings, emphasis, links, lists, code, quotes — and leaves out most of what full HTML can do. That's a feature, not a limitation, for its target use case: writing a README, a comment, a quick note, or a blog post, where speed and readability of the source text matter more than fine-grained control over every visual detail.

Where it ended up

That combination of readability and low friction is why Markdown ended up baked into GitHub, GitLab, Slack, Discord, Reddit, countless note-taking apps, and most static site generators, decades after its original creation. Nearly all of these platforms use small variations on the original spec (GitHub Flavored Markdown adds tables and strikethrough, for example), but the core syntax — headings, bold, italic, links, lists — stays consistent everywhere.
