"Art" is just another headline-filler word for "amazing." At least for children, who are the future, and geeks, who are the new trendsetter-influencer-coolhunters. Since K-12 art education is virtually dead, and no one reads books, these heavy Internet users have no preconceptions of art and they don't follow that world's big names. A new Cy Twombly or Lucien Freud painting won't get attention on Digg (Chris Ofili maybe, for the controversy), but a painted Lamborghini is one of the social news site's all-time favorite "art" posts. But it's not all bad. The Diggbrow movement isn't destroying art any more than the Dadaists or post-modernists did; it's reinventing it.
