I just heard this episode myself yesterday. I always enjoy what Simon has to share. I see that you like sharing material like this and am working on a project here on steemit called subcommunities. I'm the developer of this idea and am looking for collaborators. As an Initiator, I have chosen to dedicate my first subcommunity to this kind of material and am giving it the name "Exoteric Wisdom". If you might be interested, here are two small articles on the idea.
