@trueleo@niu.moe How you pointed out, most people interact mainly on his own Instance. But having access to a different, federated one, creates a kind of 'surfing' between what people on my Instance say and what other people from other Instances say. It's like talking at home but then go out to talk with others.
There are too different communities to generate a federated TL with a single point of view.
The only thing that can exclude somebody from being federated is disrespecting others.
I can see things on the federated TL which I don't appreciate, but until it's legit content that is respectful to others it's ok and also something that can help me to navigate in different points of view.
