The point you're painfully missing is that success of a company (including Groupon) isn't dictated by how much or little technology they use. If you feel Dairy Queen was a bad metaphor for that, then I apologize for your confusion.

Sure, Groupon is successful, but is it sustainable? To me, it's not a good business model because it could be easily copied, easily replaceable, and anyone could do it. Short-term success doesn't translate into a sustainable business model.
