Underrated benefit of lemmy is like minded people will tend to join the same instances and if I don't want to interact with those groups I can just filter the whole instance.

People talk about filter bubbles, but there's a nuance here: on Lemmy, you're not being served up whatever the platform owners think you should see from an opaque algorithm. You're going to, by default, see cesspool content. You have to choose to block it.
