I’ve recently tried to use peertube and I think it could improve a lot if it showed all the content in all instances. But instead you have to look around many instances to try and find something you like. Then there’s other thing, it can’t suggest content if it doesn’t know what you like and without sharing the data between the instances it doesn’t know anything about anyone. If the user data was encrypted and shared between all sites, when you log in it could use the now decrypted user data to suggest content. Or maybe it can share the data with third parties, I don’t really know.
Those mostly sound like anti-features to me, i.e. the typical dark patterns used by Youtube to feed you a never ending stream of advertisement.
In one extreme there’s youtube that wants to make you addicted and in the other extreme is a platform with no algorithm to suggest content. I would like something around the middle. But that was just an example. I wanted to focus on why each instance focuses on a different community of people instead of trying to bring them all together.
Because that’s the point of federation that each instance has it’s own unique selling point
