I think it is quite simple. Hacker News. News for hackers. Not in the "hacking" Hollywood sense of computer crimes (although there's some of that, too), but in the sense of intellectual curiosity.
Probably more than 70% of your post's impact will come from a catchy headline. People will be curious about your headline, and click through. And then, upvote if they find it interesting.
If the post is interesting but the headline isn't, then, well, bad luck.
Once a post gathers enough momentum, it goes to the front page. Then, there are a thousand bots on Twitter, Bluesky, Mastodon, etc, that repost articles that got to the front page, and it gathers even more momentum from a large portion of technologists that don't have an HN account but follow these bots.
