The most fun part of the early internet was the feeling that it was the Wild West. Lawlessness and fun. Obviously, rules are needed to keep things under control, but I agree that erring on the side of having fun isn’t a bad thing. It’s more inclusive and it lets people express themselves.
One of my favorite things to see on Lemmy is people who lurked on Reddit but feel free to talk here. Being too heavy-handed with rules might discourage those people from contributing.
