I don't know, but the commenter would be wrong. Art is art regardless of its credibility in "the art world," whatever that means. I suppose they meant they couldn't be as famous as Jackson Pollock for doing what he did, which seems to be confusing the value of art with the value of celebrity (the "ability to be taken seriously".)

What made Jackson Pollock's work art was the intent behind it. What made him and others like him famous was the CIA (as inevitably mentioned elsewhere in this thread.)
