I'm on a bunch of different instances, mostly absorbing the zeitgeist of each. Some mutuals across several instances, others on only one.
Each instance has its own community, its own zeitgeist which reflects a facet of your personality. Specific interests, mindsets, etc.
On twitter, this granularity is absent. You either follow someone entirely, or not at all. Here, you follow parts of a person.
You may follow their politics on foo.bar, their healthstuff on baz.quux, but not even know about their AD on fibble.wobble.
"Follow" becomes a spectrum. There is a greater surface area for converging interests.
@Pookleblinky Except I'm not sure that most people will be that granular. People will probably post stories about their day in the conlang space, politics-adjacent things in the social space, etc. I think people often think of themselves as one unitary person, so may not partition by subject like that.
It might happen a bit more if there wasn't the clunkiness of switching instances. Maybe a dropdown in the text box of "Where do you want to toot this?" would help?
