Jack Dorsey says it's time to rethink the fundamental dynamics of Twitter

Twitter CEO Jack Dorsey took the stage today at the TED conference. For most of the interview, Dorsey outlined steps that Twitter has taken to combat abuse and misinformation, but Anderson explained why the company's critics sometimes find those steps so insufficient and unsatisfying. "It's democracy at stake, it's our culture at stake," Anderson said, echoing points made yesterday in a talk by journalist Carole Cadwalladr.
