NEW YORK ( InvestorPlace) -- A key to Groupon's ( GRPN - Get Report) success has been the media savvy of its CEO and founder, Andrew Mason. He certainly knows how to spin a quote.

  • But with last year's IPO, he had to abide by the "quiet period." According to this arcane rule, he couldn't make any response to his critics regarding the offering (and there were many!).

  • So with the quiet period over, he has wasted little time in getting high-profile interviews. One was actually with 60 Minutes. In it, he compared the IPO process to a wolverine's skin being melted away.

    And this week, Andrew gave another memorable interview. This one came at the Digital Life Design conference in Munich, Germany. And yes, Andrew had some more colorful metaphors. Perhaps the most interesting was his belief that Groupon is a "cyborg." That is, the company is more than just a set of cool algorithms, a la Google ( GOOG) or Zynga ( ZNGA).

  • Instead, Groupon has an important human component. You can actually call the company and talk to somebody!

    Indeed, it has over 10,000 employees, with 7,000 in other countries. No doubt, this would be incredibly hard to replicate -- and as a result, it represents a major barrier to entry for the thousands of other daily-deal sites that are trying to get traction. After all, a variety of big competitors, including Facebook, Yelp and OpenTable ( OPEN), have scaled back their daily-deal efforts. Perhaps they need to remodel themselves as cyborgs.
