I liked the positivity of the community for the most part. Reddit, to my mind, was the only largely non toxic form of social media and that will be hard to replace though I’m liking Lemmy so far.
I always liked getting into micro communities and hearing how they talked about their worlds. That might include life in obscure (relative to me) places around the world, getting into the weeds of various occupations I’ll never work in or learning about the fine details of hobbies I’ll never have. Real people having good faith conversations about highly specific things relevant to them.
