You can see posts from every instance that your instance has federated with. For example, I, on toast.ooo, can see posts on lemmy.world, lemmy.dbzer0.com, and sh.itjust.works because my instance federates with them.
You can’t see posts from instances that your instance has defederated with, though, nor can you see posts from instances that have defederated with yours. Think of it like cutting one of those thick undersea cables that connect the internet across continents.
There’s a lot to consider when picking an instance; lemmy.world is a good default, so that’s probably why Voyager directed you to it, but don’t be afraid to switch to another instance of you think it’ll serve you better!
Bluesky is building their own thing, called the Authenticated Transfer Protocol, or atproto
for short.
Federation is planned, but there are still behaviors of atproto
that are as of yet undefined, and need to be defined and ironed out before Bluesky’s primary network is open to federation.
The issue is that a good number of products are only available through Amazon, and a metric ton of services that people depend on are owned by Google.
Just saying “don’t use Amazon or Google” is almost tantamount to saying “don’t eat food” or “don’t drink water”.
Should that be the case? No. But right now, it is.
I feel like if anyone attempted to bomb an American TSMC plant, there would be far larger problems on the docket to come.
