I know you're kidding, but I think it's actually more nuanced.
Jokes in HN comments typically don't play well if the whole point of the comment is to make a joke, but if you make a joke in service of a substantive point or attach a joke to an otherwise meaningful comment, there's usually a good response.
I've come to appreciate HN's cultural norms around jokes because if you compare discussion to something like reddit, the top comment is often just a joke or a pop culture quote and then a massive thread of people just talking about the joke or reference rather than the actual story. I think HN's norms do a better job of fostering curious discussion.
The HN version of that is that the top comment is often an analogy and then a massive thread of people just talking about the analogy rather than the actual point.
I think HN can be quite forgiving when it comes to jokes, as long as they are genuinely funny and fresh. What doesn't go well is predictable reference humor and tired old memes.
