Nice writeup. I think the people who are good at twitch streaming are charismatic and/or funny. Being entertaining is awesome, but isn't necessarily the same as being good at reasoning through problems or engineering good software.

As a watcher of such streams, be they game session I wonder how people don't see something and go crazy because they can't actively participate - the author does mention that some people will have contributed pull requests by the end of the session. :)
