Hacker News Reader

Goodhart's Law[1] in action.

I've noticed everyone posts links in footnotes, is that just Hacker News etiquette?

Ya I think so. Since there isn’t a way to make html links with a short text .

It's old-school plain-text email etiquette. The original Markdown even used a variant of that syntax for its links definition, known as "reference links". https://daringfireball.net/projects/markdown/syntax#link

That's a good one, did not know that. Interesting read.
