> (didn’t resonate), although mine is purely based on AI scoring

One reason for it not resonating might be that it’s yet another opaque algorithmic feed in a moment in time where people are getting sick and tired of them and wary of their manipulative features. And HN is so inundated with AI submissions that having yet another Show HN about it is uninteresting to many.

Would you visit HN if it were just a link aggregator whose ranking was decided by hidden logic of a machine? A lot of people wouldn’t. We’re a social species, there is value in human curation—especially when driven by the community—that’s inherently lacking from algorithmic curation (AI or otherwise).
