Bluesky released early documentation for the "AT Protocol" (atproto) a few weeks ago, and I've been noodling around with it.

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?
