So, I find people talking about blue sky confusing; if I search for a bluesky user to follow via Mastodon, I don't see them come up. Does that just mean my server isn't federated with them? I'm on mastodon.online, which I think is one of the biggest instances.
It'd be cool if I could actually interact with blue sky but it's really not clear to me how it works if I don't have a blue sky account and am interacting externally
