Yes, just to add, PDS is the easy part.
Here's a better way to view the network.
@_elena there's also no need for SSO (Single Sign-On) to mean “single identity” —as long as YOU are the one that controls the sign-on. See e.g. the Nomad protocol:
Should be interesting
@_elena Interesting point!
Personally, PDSes are one thing I really like about the Atmosphere/ATProto. Being able to log into multiple apps without needing to manage multiple accounts is pretty convenient, and enables more developer experimentation.
Here, you either create a new fediverse platform, meaning you need to create a new account, or maybe a Mastodon browser plugin or web app, because not many want to put in the effort to support all the different APIs.
@_elena @jaredwhite To be fair, it is possible to host all of the ATProto infrastructure for much cheaper with the same trade-offs as with a fediverse server, where you get an incomplete view of the network.
@_elena @jaredwhite That is, with one exception.
Apparently the built-in DMs are stored off-protocol on Bluesky's servers. So, yeah.
(But they are apparently working on that.)
