But upvotes and downvotes are a form of regulation (global same enforcement for everyone), and not a form of market liquidity.

They'd be market-liquid if HN learned an embedding of who-upvotes-what and created a bubble for each user where each sees the comments they'd upvote.

In facebook/instagram/tiktok/linkedin your comment would work.

(On an unrelated not, I sort wish HN would do that for posts; as I'm not interested in 95% of what makes the HN frontpage. Please bring me back hardcore technical content, please let me ignore societal/self-development/CSS/drama/etc posts. No judgement but I just don't care about that content.)
