Thanks for the informative comment!

I apologize, I wasn’t entirely clear in my first two questions. They adhere to background checks for work. I’ll obviously have to spell out my whole username with @lemmy.world. But if someone who isn’t as well versed would find multiple durd_s and many have posted or commented something that wouldn’t be in good taste, this isn’t good for me.
I’m not sure if I’d be allowed to explain what the fediverse is and how it works.

Registering my username on other instances is possible, but not very feasible as there are quite a few instances already, and I venture that more are created by the hour.

Heh, conflicting information now from what @minnix@lemux.minnix.dev said :)
If my data is federated as well, why not also my login information? Allowing me to login on any instance I want with my regular user. Assuming that my home instance has instructed other instances (and they allow it?) to do so.

This would make me, and I’m sure more users, at ease with using closer, smaller, less popular and probably faster instances.

This is good, but requires my home instance to be alive while I migrate.

Thanks, I remember when everyone was leaving Twitter for Mastodon. I couldn’t understand why all the different servers and what they had to do with anything. I do understand more now obviously.

Is federation automatic or do I have to apply to each instance? I’m thinking I could self host and only rely on my own eptitude and internet connection.
