Sure, but that's it's own not-quite-markdown thing, which is extra annoying because it's just close enough that people think it is markdown and do things like writing code blocks with ```. IMHO it'd be much better to just actually do markdown, or at least a strict subset.
That's only very limited support of the most basic forms of formatting. It's the year 2024, and Hacker News can't do better? Even the blog post above, from 2006, uses a LaTeX plugin.
Yeah but could it even be changed at this point? I'd imagine that once the ball gets rolling, changing any kind of formatting rules for a site with over a decades worth of (hundreds of thousands, tens of millions? ) of posts would be pretttty hard to get past committee
I would strongly favor writing a script that went through the database and rewrites existing comments from the old to new syntax; I believe in this case that's doable. And you would want to message it ahead of time of course. But with those things done I think it'd work fine, especially because I suspect virtually anyone who's gotten used to the HN formatting codes is already familiar with real markdown so it'd be a relatively painless transition.
