I honestly believe that most people do the best they can. Nobody sits there and thinks, "Time to make some sucky art."

What's happened, I suspect, is what has happened to the entire Internet. Everybody's online now. Before, you needed a certain level of expertise and education just to get onto the Internet. That's no longer the case. There's no gatekeeper any more; the unwashed masses are online. Renderosity is much bigger now. It will never be the same as it was.
