Let me interject for a moment to shut down the Diablo 3 Auction House nonsense right now.

That's an extremely misleading article filled with conjecture by the author. Look at the actual quotes; Ryan never said anything about Diablo 3 and never said anything about players selling content. What he has said is that sharing content between players is an important part of what we're building, to which end we're working on bringing the exchange functionality from Sims 3 directly in-game rather than requiring it to go through a website outside of the game. What we're not answering yet is questions about how that functions, and the author seems to be using that as a platform to speculate on what we will do.
