To me art has always been "an interesting idea". Decorative things that take skill to me are crafts. Sure, it's a water color of your garden, but what does it tell us about the human condition? Sure, it's skilled... but it's empty. Give me Jackson Pollock or Picasso. Give me a new way to see the world. Pure skill to me is as impressive as cup-stacking personally.

Not saying you have to agree, but it is a distillation of how some portion of the world sees the world.
