Joshua Kopstein has a good article in The Verge about the problem of making a buck off of art meant to be consumed via the internet. He considers the success or failure of the micropayments model, through the snake-eating-tail conundrum of 0-Day Art (dedicated to keeping art online) being included in an Art Micro Patronage show (which limits access to work by non-patrons, after a show has ended).
He mentions Lauren Cornell's GIF-selling gaffe at the Armory (as we are now going to describe it, for want of a real explanation). Cornell continues to insist the artist made her take the GIF offline so the collector could have it locally (which isn't how the artist has described her methodology) and even got an awkward disclaimer attached to the end of Kopstein's article!
