Assume that everyone follows roughly 150 people and is followed by the same, and that your average person has 10 notes per day + some number of interactions that may have a smaller audience.
If we follow the specification as written and don't use a sharedInbox that comes out to every person sending 1500+ messages a day and receiving ~1500 messages a day. About 6 MiB of data.
Across the entire fediverse with 1.5 M users you'd be looking at 4.5 B messages. 4.5 TB.

Afaics a similar scaling issue had been handled in the past by NNTP, i.e. #newsgroups. I wonder if we could look at oldish NNTP to learn a trick or two
It should be clear now that it was and remains a catastrophic mistake for people to view privately owned social media platforms as any kind of public resource. People didn't know better a decade ago. They have no excuse now.
I'm going to disagree with that last bit - people did know better a decade ago, at least some of us. Social spaces on the net long predated the arrival of big tech and commercial social sites - we used email and #newsgroups and the Unix talk and finger protocols and #IRC and other things to keep in touch with people, from the person at the terminal next to yours, to someone at a university halfway around the world.
We warned about the big #commercial sites when they arrived.
I've been spending a lot of time on #Lemmy and #kbin and the communities both here and there remind me a lot of the communities that I encountered in #IRC chatrooms and #newsgroups back in the day, ie. highly nerdy, highly tech literate.
The #fediverse creates a lot of interesting new technical and social problems, but it also solves the problem of how to get big tech the fuck out of my social media. I think I'll stay.
