Sure, you always need a money-spinner at the end. As I was trying to say in the last paragraph of my post: when you get people stick to your service, it broadens the realm of possibilites for monetization. For instance, the online collaborative studio could have some premium features (specific editing tools, extra storage... I am thinking out loud). Another example: when you get half-million users coming back every week, music labels or festival organizers might be ready to pay to get their advertising to the right audience (musicians, music fans) - see Pitchfork or Rollingstone.com.
