I only have experience with Lemmy, it’s kinda my daily driver for social media. It functions well, I enjoy my instance and the admins there.
The political rhetoric can be a little exhausting, especially with it being election year. The culture clashes between different instances can cause friction.
Example, this is on Lemmy.ml, and I think the admin and moderation policies on .ml are patently absurd. They also have a bot that auto edits comments to remove no no words, which is… well stupid. I would not be surprised if this comment gets removed for the above remarks.
But that’s what’s nice, Lemmy.ml admins can’t ban me from Lemmy, only .ml, and if I don’t want to deal with .ml anymore I can just block the instance. We surpassed them in MAU anyway. My instance doesn’t defederate on ideological or political lines so I have that option.
So, overall I’m enjoying myself. I’m concerned about the longevity of the platform and the extremity of political rhetoric that has to permeate every single post, but I’m hoping that dies down as Lemmy Balkanizes. That’s already started with hexbear defederating from lots of instances.
