That's true in theory but the number of people like PG who can setup such a valuable resource and not care about whether it costs them money are few. Most people who create outlets for art online or elsewhere have bills to pay and money becomes a factor. It is a very risky and low-profit business bringing obscure art to the masses. What is more likely is what happened with Myspace - it was a new, innovative way for any musician to create a presence for themselves online, where millions of people were also spending time exploring. But they chose not to limit it to only high quality artists and eventually the people who spent more time "friending" others than they did actually making a quality product achieved more through the platform. Creating something that works differently when this is the natural flow of such platforms is very challenging.
