Show HN, being used by people to share the cool things they create was an important part of creating of a community, aka always having people which would find interest in what you share.
It was a channel to push novel unpolished ideas to the world. It was one differentiating thing from other places where self-promoting is usually forbidden. Here it was welcoming people to take a more active role and create things.
Now it's just screaming into the void, the only feedback you get are email spam from LLM companies trying to push their solution to help you promote your content.
Sharing projects is also just feeding your competitors and killing the potential of your ideas, now that a clone is less than a prompt away.
I don't know who still look at this page, but then if you want to get past it you now probably need to turn to the dark side with some form of cheating, which is also conveniently easier than before to have bots spam about your product everywhere on the internet.
Show HN are now becoming the reverse, instead of feeling heard, it's even more isolating than before because when you put some effort and if even in the niche market where it's suppose to gather attention it doesn't, so you think you are not welcomed here, don't come back and look elsewhere.
