There are some people who don't know what art is or what defines an artist. I've come across someone who says that art is even completely "man-made". And that just because it's appealing to someone, that doesn't make it art.

So, the question is... What Is Art? The dictionary definition is:
"the quality, production, expression, or realm, according to aesthetic principles, of what is beautiful, 'appealing', or of more than ordinary significance."
So, who get's to define what art truely is? Not people who are ignorant to the basics. True, Art has changed drastically with the years.
