@nedwharton though, on the other hand, if you go to mastodon.social and try to look at their federated timeline, you just can't.
It's literally so fast, it's unreadable.
Keep in mind that I didn't mention boosts or replies to those who are federated.
Boosts and replies, if they aren't federated by following, are federated on a "per post" basis.
So if someone boosts 1 post, it doesn't mean you'll see all posts from that user, but at the very least, you'll know the user exists so you can follow if you choose.
Things are very nuanced here and there's some fine lines of what's useable and what isnt, in terms of a federated timeline.
This place is still fairly new. I think we'll get there, in time.
