In this episode, Samuel Arbesman speaks with Brendan Schlagel, a builder obsessed with learning and community, and the cofounder of Hyperlink and Leaflet—projects devoted to helping people learn together and share knowledge in public.

Samuel and Brendan trace the history of Hyperlink and the learning communities it sparked, and how that work ultimately led to Leaflet: a tool designed to make publishing and sharing online feel effortless again. Along the way, they explore learning and education, the strange power of lists, personal canons, antilibraries, practical advice for connection (online and off), and even why a two-person book club can be unexpectedly transformative.
