Bridgy Fed’s Bluesky integration is now in beta, and makes it possible to connect your account from the Fediverse to Bluesky, and vice versa.
There’s still some quirks, and every bridged account has to opt in to it, but it’s a promising moment for people that want to communicate across networks.
They have been saying that this is an implementation detail that will change when they open up that part of their implementation. Which is nice, but until that happens I’m only lukewarm in my optimism for Bluesky and the AT protocol.
On the other hand, every federated network has converged on a central host for the vast majority of accounts and data. That host has outsized influence over the standard used on the network and unencrypted acess to the majority of data. So I’m not sure what really matters to what extent.
