Bluesky released early documentation for the "AT Protocol" (atproto) a few weeks ago, and I've been noodling around with it. Technically, it strikes an appealing balance between rigid cryptographically signed content-addressable storage on the one hand, and familiar web-friendly schemas and integrations on the other. But at an ecosystem level, there are already a bunch of existing open social media projects. Does atproto bring anything interesting to the table? How might it fit in compared to other similar protocols?

How do we talk about atproto to non-developers?

The beauty of AT Protocol is that all of your data from different apps is available on your PDS, your own folder on the internet containing your stuff as JSON. This means that you can switch which app you use to view that data, without losing anything. It also makes it very easy to make connections between data stored using different lexicons, or just display activity in one place. Sifa does a nice job of this on your profile page. For web developers, and people who understand webhosting, the concept is reasonably easy to understand. I know that any atproto app I join is going to store data in my PDS, any other people will be able to see it.
