We’ve made it to our 300th weekly episode! While it’s easy to congratulate ourselves for being among the few podcasts to produce this many shows, Jim and Richard are most proud of our extraordinary range of guests.

During our first six years together, we've often highlighted out-of-the-box thinkers, who share ideas that are too rarely discussed: People who speak about solutions through an independent lens— neither firmly left nor right.

For this episode, we revisit interviews with six guests— or roughly 2% of all the people we've spoken with for "How Do We Fix It?" We begin with the public intellectual and problem solver Philip K. Howard, who was our very first guest. Others featured here are Claire Cain Miller of The Upshot at The New York Times, Mike Rowe, who became famous with the TV show "Dirty Jobs", science evangelist, Ainissa Ramirez, Jerry Taylor, President and Founder of The Niskanen Center, and R&B musician Daryl Davis, who has personally persuaded more than 200 men and women to quit white supremacist groups.

When social media burst on the scene, many of us were in awe of its great potential. For the first ten years of Facebook, public reaction to this new form of communication was overwhelmingly positive, but now that we have a better understanding of how social media is shaping our world, there are growing calls for fundamental reform.

Should tech monopolies be cut down to size and broken apart? Or is a much more careful, nuanced approach needed from Congress?

MIT Management Professor Sinan Aral has spent two decades studying how social media changed American politics, the economy, and even our personal health. He is the author of the recent book, "The Hype Machine". As an entrepreneur and investor, he has a deep understanding of the perils and promise of social media. We publish extracts from his interview with the podcast, "Democracy Works".
