Markdown-style Footnotes - using Markdown to easily make footnotes in your post

How to Write Markdown Footnotes on Forumosa

Ever wanted to add footnotes to your post to explain something without interrupting the flow? You can! Discourse supports Markdown-style footnotes, and they’re super easy to use.

Here’s a quick guide:

The Basic Syntax

There are two parts to every footnote:

  1. The reference — goes in your main text.
  2. The definition — goes at the bottom of your post.

Example:

In your post, you would write:

Taiwan has the highest density of convenience stores in the world.^[As of 2023, Taiwan has one convenience store for every 2,300 people.]

This will automatically position the footnote content (i.e., As of 2023, Taiwan has one convenience store for every 2,300 people.) in a numbered list at the bottom of the post after you hit submit. And it will automatically create a clickable footnote link, like this:

Taiwan has the highest density of convenience stores in the world.[1]

So, why use footnotes at all? They’re great for:

  • Adding sources without cluttering your post - having all external links grouped at the bottom of your post can be easier for people to read
  • Sharing extra context without distracting readers
  • Adding humor or commentary “off to the side”[2]

btw: A brief history of footnotes on the internet

Footnotes have been around since the days of monks scribbling in margins — but on the internet, they’ve taken on a life of their own.

  • Academic origins: Originally meant to cite sources in scholarly texts, footnotes were formal and dry.
  • Internet remix: Bloggers in the early 2000s[3] started using footnotes for humour, side-comments, and witty asides.
  • Forum fun: Footnotes became a low-key way to slip in sarcasm or extra context without derailing a main argument.

Even today, footnotes are a beloved tool in the hands of nerds, writers, and chaos agents who want to say “by the way…” without actually saying “by the way…”

So go ahead — drop that clever side-comment or citation[4]

  1. As of 2023, Taiwan has one convenience store for every 2,300 people. ↩︎

  2. Like this one: I told my wife I was writing footnotes on the internet. She said, “Ah, so you’re finally putting your tiny opinions where they belong.” ↩︎

  3. especially on sites like kottke.org and MetaFilter ↩︎

  4. Just remember: Footnotes can be like scooters in Taipei — nimble, occasionally cheeky, and always finding space where you didn’t think there was any. ↩︎
