I have things to say and share as well, and the product needs to tend to that in order to have me be interested in staying on as a user.
There are other platforms where I can follow AND be heard. HN is one of them. I've shared several projects that got to the front page. Whenever I post projects to Twitter, even put a shitton of hashtags on it, and all I get is dead silence for my 50+ hours of work put into something honestly interesting, while some "influencer" gets 100K likes and 10K follows for their one-line low-effort armchair tweet bashing Elon Musk that they spend 10 seconds on. That discourages me from wasting more time logging into Twitter.
That's just my experience as a user. If they want more people like me on there, they need to fix their product to improve discoverability of small creators. If they don't, that's fine, I don't really need Twitter anyway.
