What I don't understand about this argument, every time I see it, is how do you think Trent Reznor, Louis CK, Radiohead, etc. got to the point where they could trade on their good name?
Do you think Louis CK was just sitting on his ass and then, BLAMMO! FAME!: he was a superstar comedian?
No, something tells me all these examples are of people who worked their ass off under the traditional system, to a point where they can now buck that system.
So what will be the answer under this new "non-traditional" system? Same as it ever was: work your ass off.
Or more to the point. How do you crowdsource if you don't have the name recognition and track-record to trade on? You better be one hell of a salesman.
