Lemmy seems somewhat confusing to those who rarely or never used Fediverse (myself also rarely use Mastodon tho), but after I short while I get the hang of it tho. My instance is at lemmy.world, Its UI after a time trying is quite unstable; for example, a post's karma is fluctuating at time, sometimes from over 1k drop down to negative, and upvotes aren't recognized until you reload the page,...
