A better analogy for your comment would be in a Twitter conversation, you replying to an OP with a quote tweet of a similar comment you made in the past. Yes, I do find those annoying.

I'm really not concerned whether the severe drop in SNR comes primarily from entryists from Reddit, Twitter, or some obscure web forum (likely it's diffuse). But on its face, the rise of jokes, puns, and other low-effort comments - having to collapse threads to find the comments with something useful to add to the convo - is very reminiscent of Reddit threads, where entertainment and cheap memetics are valued equally or greater than logos. HN used to distinguish itself by obliterating that type of cruft, with a "lurk moar" sting, but it no longer does thanks to lazy gatekeeping.

Now I'm not going to change any of this by pointing it out - the horse bolted years ago and closing the stable door won't change anything now - but you should know the "signals" you're intent on following are worthless as they're from a Reddit-lite entity, not HN classic.
