On this podcast, we regularly engage with questions about redesigning social media networks to make them more democratic, pluralist, and prosocial. One hypothesis people have about how to do that is through the decentralization of platforms and the introduction of middleware—tools built to give users more control over their social media experience and, thus, more autonomy in how they engage in public discourse. In this episode, you’ll hear a discussion with one entrepreneur building middleware for Bluesky: Rudy Fraser, the founder of Blacksky Algorithms and a fellow at the Berkman Klein Center for Internet & Society at Harvard University.
