I just have biases against other servers. For example, .world users tend to act a lot like redditors which I dislike.
.ml users are more likely to tell me about the glories of communism than any other discussion. Yeah I get it, the ml stands for Marxist-Leninist, great job guys.
.dbzer0 folks are more likely to profess the greatness of FOSS solutions and discuss Linux distros, but I'd rather have that conversation over and over again because it's usually pleasant and I learn something new every time.
