Yeah it's the lack of vote counting, more than the lack of downvotes, that I really appreciate. (Not to say I really miss downvotes or anything, I just really don't care either way.)
I'm also on Tildes and they also lack downvotes, but once you've been on there a week you get the ability to label things (noise, jokes, malice), which sort of functions as a more nuanced downvote button. But they share the lack of overall karma score, which keeps that same nice non-performative vibe.
Note that it might take a while though, so if anyone wants to get this done before the 30th (so you can use API-based tools to wipe comments), request it ASAP.
I requested...maybe two weeks or so ago? And it only came through today. So get to it y'all
