BlueSky is its own thing with its own federated protocol called ATproto. They have an explanation in their docs on how it works, different features. There’s a bridge between the two as well, a bit janky but effective.
It’s a federated protocol, but the network itself isn’t meaningfully federated, and is basically just Bluesky (the company) infrastructure. Hopefully that changes, because until then, it’s still a centralised social media platform, despite the underlying technology
They have no reason to change that. They will long term want the exact same thing that twitter has, access to all user data and control of the platform.
Rumors are indicating that they want to offer some subscriptions to users(domain registration and hosting of various bluesky components).
The company is currently TINY, under 50 employees. So as long as the infra costs stay low, it won’t take much. If enough users get vanity domains, and they get some govt/enterprise accounts for hosting bsky.cnn.com and such.
So the idea is that they want to get to some ethical monetization strategy before releasing the software to aggregate content is released, and federation is enabled.
No, not unless the person whose posts you want to see opted into bridging their account.
If both parties bridge their accounts they can follow eachother, or if one person bridges their account others can follow them.
I don’t think you can see boosts of stuff not on your platform though, and I don’t know how interacting with a bridged account works if both of you are bridged. If only the person you’re following is bridged they definitely won’t see it, but I don’t know if that changes if you’re both bridged
