I like what Seth Godin says in his book, Linchpin.
"Tom Peters, corporate gadfly and writer, is an artist, even though his readers are businesspeople. He's an artist because he takes a stand, he takes the work personally, and he doesn't care if someone disagrees. His art is part of him, and he feels compelled to share it with you because it's important, not because he expects you to pay him for it.
Art is a personal gift that changes the recipient. The medium doesn't matter. The intent does.
