the upvote/downvote system is still problematic, because its roots are in exploiting addiction mechanisms via giving people that dopamine rush when they get high upvotes, and making them chase that high again.
I really miss the pre-social media days when we had forums instead of...whatever reddit/lemmy are, when there was no upvotes, no karma, no nothing. You just made a post, and people replied to it. interaction without gamification.
