It’s not stop complaining as much as it is please contribute something of substance instead of venting hot air into a comment thread where everyone is already aware.
I'd rather read it's slop, it actually adds something to the conversation.
I'd say "imagine if half the posts on HN aren't worth your time" but this is genuinely how it feels nowadays. I'm not sorry
The problem is that not everyone thinks like you. You're dictating what is and isn't a signal to others. OP left a comment to signal to people like me. It saved me a click.
1/3 of articles warrantying such a comment means it is still important information. If it was 100% of the articles I would agree that it gives no information, but with 1/3 one cannot claim it does not contribute information.
