Yes. I think that's notmal, no? Some people have more time than others, and care more intensely about some topics.

Others are bots and paid shills too, just trying to earn a living.

I swear there is one dude who is like a frequent news reporter, I see his name nearly all of the time around the instances. But yeah there seems to be just a handful of people who represent the minority that just chat away.

Lemmy.world is defederated from the major Marxist instances, so you might want to join a different instance for a fresh look. Lemmy in general is small enough to be dominated easily, what helps this is finding a good instance and treating said instance like a community with different tags, rather than treating communities like subreddits.
