Yet despite the clear creation of echo chambers, which I think is inevitable given how freedom of association works so smoothly and easily online, the Fediverse forces them all to “live next to each other”.
It’s not an entirely separate service I need to go on if I want to see what all the Nazi kids are up to these days.
This forced adjacency and inability to create any blocks stronger than defederation (which is pretty weak, really, compared to what other services can do) is going to have overall beneficial effects in the long-run, I think. Though it’ll certainly cause its fair share of headaches too.
