I immediately thought of this quote too. I see this as sort of a honeymoon for Groupon while people figure out how it really benefits (or doesn't benefit) their business. Over time their margins will probably drop considerably, so why shouldn't they take what they can get now? I can see how this sucks for small businesses who get flattened by the runaway train, but is it Groupon's responsibility to sabotage their own business model by performing due dilligence for their customers? From what little I know everything seems clearly above board.
