I think even better, you should be able to sign into any instance via some type of centralised federated login, though I guess the argument is you can’t do that in multiple email clients as email is the most popular federated example.

I like the concept
But it feels very much like its been designed by nerdy developers and has had little to no-input on user friendly design.

The federated idea can work but it needs to be more seemless than this.

1. Communities with the same name should be merged when viewing it from any instance, so you can see all the posts from these communities, they can be moderated seperatley and for advanced users you should be able to select which communities make up the merged community.
2. By default you should see all of the merged communities in a central place and be able to subscribe to them easily, at the moment its handled different per instance but you have to seek out these communities to subscribe or follow them.
3. I strongly believe there should be a centralised log-in system, so you can log into any instance with an account from another instance, this means if your instance goes down your account is centralised and is safe.
