Last year Krista Tippet, the host of the radio show On Being, interviewed marketer Seth Godin, asking about his perspective on art in the digital age. Not surprisingly, Godin's responses were interesting, informative and in keeping with his previous writings on the subject.
I found one comment in particular to be spot on:
Art is by people who have a compass, rather than a map — who have an understanding of true north and are willing to solve a problem in an interesting way.
