One of the favored analogies of the people on the Rhizome chatboards attacking current art on blogs and WIKIs is "using animated GIFs and default blog templates is like using acrylic paint and prestretched canvases!"
Unfortunately the slacker aesthetic invaded the art world long ago.
Thomas Nozkowski's paintings of the early '80s were all on art-store canvasboard.
More recently, that's how Eric Doeringer works--paint and ink jet prints collaged on prestretched canvas. No rabbit skin sizing and ground pigment for him.
It's hard to explain attitude to completely earnest people.
