Your comment is spot on except your hyperbolic and unnecessary attack on social security.

Groupon figured out a way to sell a dollar for $.50, and they use money from new investor's to pay the old-- just like a ponzi scheme.

Also what does Groupon have? A few thousand merchants, a few million email addresses, no patent portfolio, no moat so to speak-- and the fact they need 8000 employees mostly dedicated to sales means they can't scale well--ever.

Most likely Groupon has 6 months to a year before the money evaporates. If not then they end up like Avon or Snap-On tools at best.
