Your explanation of federation that it "works like email" will be misunderstood
The linked post shows how most non-tech people's understanding of email is very very different from most of the people here.
You're viewing a single thread.
"you know how you can't talk to someone on Twitter.com from facebook.com? But you can email from your @gmail.com to someone with an @yahoo.com address?
That's the difference, federated social media is like email in this way."
I'm mostly sure even my elderly parents understood it when I said it...
till they throw you the curveball that they can indeed talk to someone on twitter from facebook.
And you know how, when you subscribe to a mailing list, you will only receive new mail sent to the list if your server happens to “federate” with the sender’s server?
Oh wait, that’s not how e-mail works.
Email providers absolutely block other email providers who abuse their system.
I’m not talking about blocking, but about being unable to see all replies to a post unless you open it on its home instance, which happens all the time on Mastodon.
