Are Mastodon instances connected somehow? For example: can I communicate to another user in another instance in this instance? It seems like that should be an option/feature of some sort.
@logonoff you can follow and mention other people on other instnaces
@logonoff if you follow someone from another instance your instance will pick up their messages and they'll show up on the federated timeline
@logonoff yes you can
@logonoff They are indeed linked. It's called federation, and it's automagical.
@logonoff For example: you're on .social, I'm on .cloud. I saw your toot and replied.
