This episode marks the fifth anniversary of the Rationally Speaking podcast! To commemorate the occasion, Massimo and Julia hold a live-streaming Q&A in which they respond to questions submitted via Twitter. Topics include: What's the best book to read to improve your rationality? What's the biggest problem with the skeptic community? How can we get politicians to be reasonable? And how can you be so sure that other people exist? Halfway through the show, Massimo makes a surprising and poignant announcement.
