Hey, I am currently trying to understand a bit better what the Activity Pub allows and what it doesn't as I am preparing a presentation on that topic.

On Lemmy I can join other servers without having to recreate an account. Does that also work for across Activity Pub supporting software? Could I join a PeerTube page and then post there? Could I upload videos? Could I join Mastodon or Pixelfed and post images?

Oh, I agree. I meant SSO in the second sense: that there are external Identity Providers that you can use to create an account at different servers hosting different kind of fediverse experiences - be it Lemmy, PeerTube, Mastodon or ... I understand the issue you are describing first, but I haven't had that problem yet. Sounds like it could be fixed with a simple redirect - but I guess it is not so easy to figure out whether you need a redirect in the first place.

Yeah, the redirect is easy. The hard part is that I'm just some unauthenticated user on whatever.net or something and I clicked the 👍 button. That could pop up a box that's like "hey, what server is your server?" and then I type it in. That could be done, but it's kinda crap, and we don't have anything better 😅

I think for now the easiest solution would be a browser extension "TakeMeHome" that automatically redirects you when you enter a foreign server that is federated with your home server. Should be pretty easy to implement.
