I'm honestly surprised how well it's going.
From the perspective of usually just swinging into a post from the front page, when I do see green, it's usually overtly political trolling, and dead from the start. So I had assumed new account = everyone sees your post in gray, at least for a week or two.
I don't envy the "Show HN:" case. It can be intractable, story time:
Last week, there was a "Show HN:" post for a GitHub link, made it all the way to #2. It was a Flutter app, written up as if it did all the stuff you'd want from an open source LLM client. I said to myself "geez, I knew I took too long to deliver the thing I've been working on for 2 years. the MVP version is insanely popular."
-- only after digging into the repo for 10 minutes, with domain expertise, did I realize it was a complete Potemkin village, built by Claude. And even then, I was afraid to post something pointing this out because it required domain expertise, and it could have read as negative rather than principled.
All that to say, some subsets of The AI Poster Problem now require having intimate domain expertise and 10 minutes to evaluate it. :/
Additionally, the Claude 4.6s and GPT-5.4s are better than me at posting on HN now. :/ And I've been here 16 years. The past couple days, any comment I write involving some sort of judgement or argument is by Opus 4.6 or GPT-5.4, via: 1) dump HN post into prompt 2) say "I feel $X about this, write me an HN post that communicates this but not negatively".
I'm a little ashamed to admit if you look through my post history, you'll definitely see a repeated pattern over 16 years of someone who is very negative and has a hard time communicating it constructively. They're smart enough now to extrapolate observations in the way I want to, while avoiding my own tarpits.
How about this: ask your LLM to review your post, "does it follow HN rules?", "how would others read it", "If I were the other person, how would I feel about this reply" , "is it convincing to you?" that sort of questions. That'll help, and it'll still be your voice.
And beware of what's already in context. Sometimes ideas that seem obvious given antecedents are not so obvious when taken in isolation.
My only problem with the last part is that your tarpits are you, and personally: I want to know you, not some version of you filtered or softened by AI. That to me is what makes HN great, how...jarring the reading experience can be, it's really fun and interesting to see how people communicate their ideas - I think it's admirable that you're making an effort to become more kind and communicate more positively, but fingers cross you don't lose "your voice"! :)
