This sounds pretty interesting. Would like to hear more.
I've had the idea that programming streamers could give more incentive to contribute to their project and then the best contributors end up working for the streamer. Streamer uses clout to gain users and attention from investors. The streaming also helps for transparency and logging of why stuff was done.
My only worry is that the viewers who have the time to invest in watching hours of streams aren't skilled enough in the first place.
