I’ve brought up a new KBIN instance, https://feddit.online
It’s administrated from the Greater Boston, Massachusetts area. Everyone is welcome to sign up, so long as they follow the rules
I now, because I must be crazy, have 4 Fediverse servers running.
KBIN: https://feddit.online
Mastodon: https://hear-me.social
Calckey: https://bostonsocial.online
Peertube: https://my-sunshine.video
you don’t need to visit the pages of the other instances directly. If you visit them, then no, the same login is not working.
But you can find the content of other instances inside your “own” instance. For example the main community of that instance can be found here https://kbin.social/m/feddit@feddit.online
