What happens when the person who once architected one of social media’s biggest platforms decides it needs to be entirely re-thought?

From day one Blaine Cook helped build Twitter creating the @ mention, OAuth, and numerous technologies that still quietly power the internet. Disillusioned by what social media has become, he stepped back to rethink it entirely.

In this episode, he chats with Rabble about Twitter's early chaos, the decisions that shaped it, and why he refuses to accept that these platforms can't be changed. Today he’s building a better approach to online community called Roundabout, Blaine explains why he's betting on people to get this right.
