I loved forums, and we didn't have anything, except for 'total posts' and 'total replies' for users. I like that.
I do like upvoting, but I think karma should be hidden. Maybe if you go to user profile and click a button to see the value. It should not show if you hover over the user in a discussion, like Reddit. This is too much incentive for Karma farming.
I don't like downvotes, and that's the reason I'm on lemmy.one - no downvotes here at all
I like that.
