I have live streamed some stuff before when coding, and I must say most of the people who come into a channel doing coding are really nice people who ask really insightful question, or offer good solutions. It's like Mob Programming with the internet (or as the author here says an "MMOPP"), and it also makes me a better programmer because before I even think about writing any code I'm thinking about how it will be perceived by someone else peering over my shoulder (akin to the pro arguments for TDD).
