Steven Johnson, writing for the New York Times:
It has never been easier to start making money from creative work, for your passion to undertake that critical leap from pure hobby to part-time income source. Write a novel or record an album, and you can get it online and available for purchase right away, without persuading an editor or an A&R executive that your work is commercially viable. From the consumer’s perspective, blurring the boundaries has an obvious benefit: It widens the pool of potential talent. But it also has an important social merit. Widening the pool means that more people are earning income by doing what they love.
The skills required to succeed in creative work have changed; the old gatekeepers are not the new gatekeepers.
