Personally, I prefer Lemmy over Kbin because I hate karma and reputation points. I do not want to worry about downvotes, and Lemmy feels so fresh. I can post things that will receive lots of downvotes and not need to worry about losing karma.
A karma score encourages making poor quality meme posts and comments in large quantities to gain more fake internet points. It's easily abused; Reddit is full of karma farming bots.
No downvotes was also mentioned here, but I heavily disagree. Downvotes, in my opinion are mostly a positive thing. Youtube hiding downvotes was a move towards a "good vibes only, no criticism allowed" type of environment.
Lemmy pretty much meets my ideal in this regard, it has downvotes and doesn't have a broken social credit system.
Downvotes aren't intended for the subject of the news, but for OP for making the post. If you hate the subject, I guess the correct action is to express it in the comments, or give an upvote if someone else already did.
I like the thought behind this idea but I don't think it's a good solution. It requires having a reputation score, which I think outweighs the positives here. I could also see people trying to play this system in a couple different ways, which is just plain bad for discussion culture: encourage others to downvote something without spending the reputation yourself, or collect downvotes with bait content in order to eat through other peoples reputation.
What is your opinion about Lemmy not having karma but Kbin having reputation points?
