Justin here, thanks for your interest. ;-) On the point of professors attracting grad students interested in seeing and participating in the prof's work... That's true and it is a major element of what I'm doing. Many of the people who take my courses do so to stimulate/improve some kind of personal creative or intellectual project; I write books and such alongside the courses, and we occasionally discuss strategy, tactics, workflows, etc. So it is very similar to the working relationships I had with grad students in the university. The only difference is now my students aren't hoping to land academic jobs, they just want to do meaningful work and make their dent on the world through the internet.
