Guy is hundred percent right. Lemmy is a echo chamber for a certain demographic as vast majority of users are in it.
We either have tech, or politics. Literally every topic ends up in either. We also don't have the differing opinions aspect as just about every debater talks like they're just the different shade of the same color.
Even spicy news that would make any other site a warzone of opinions just echo chambered here. Literally everyone agrees on one conclusion and random two comments that disagree with that having at least -15 points.
This was the pipe dream for many many years now. Not the first time MS is talking about it either.
It's a thing in the Linux world and it's just too costly to support and therefore most user facing distros outright don't support it.
