If there is no global username then that is a major flaw
@princessfluffy your global username is princessfluffy@octodon.social
So people on other instances would need to follow you using that user name. My understanding is you can not use that to login on other instances.
@chad But anyone can register the same username on a different instance - how many people will look at the @ extension to see that it is different - for many users this would be confusing
@princessfluffy yeah it took me some time to figure it out. That is a downfall to a decentralized social network. It's more like IRC than a typical social network on that front.
@oneoffsuit @princessfluffy For real. IRC was one of the things that brought me to learning more about computers and the internet.
