Hot take: a voting system (and generally any move toward ranking content rather than displaying it chronologically) will inevitably rot any social media platform. Just a question of time.
Of course 4chan isn’t a great system for meaningful discussions, the system skews conversations towards outrage and shock. But reddits short, quippy, in-group signaling post style that is encouraged by their voting system seems to be absolute worst way to interact with other people. HN also has this problem to an extent, but it’s properly modded and most people here seem to be not be living through their phones so it isn’t nearly as extreme as reddit (or twitter, I never use twitter but people seem miserable in a similar way to reddit users).
