···11111212I believe we are at a similar juncture with social apps as we have been with open source thirty five years ago. **There's a new movement on the block.** I like to call it *"open social"*. There are competing visions for what "open social" should be like. I think the [AT Protocol](https://atproto.com/) created by Bluesky is the most convincing take on it so far. It's not perfect, and it's a work in progress, but there's nothing I know quite like it.
