In music, which was my world before, you've got thousands and thousands of years of great ideas that have already been thought of. But the internet is basically 20 years old. So you can be way stupider and still have world-changing ideas.

Generally, what people tend to underestimate is the cyborg nature of Groupon. We are a company that has the DNA of being both a technology company and a heavily operational company.

There are over 2,000 direct clones of the Groupon business model. However, there's an equal amount of proof that the barriers to success are enormous. In spite of all those competitors, only a handful are remotely relevant.

Groupon as a company - it's built into the business model - is about surprise. A new deal that surprises you every day. We've carried that over to our brand, in the writing and the marketing that we do, and in the internal corporate culture.

The popularity of Groupon has almost rendered the group-buying element of it obsolete, because we're able to deliver so many customers that the merchants are very happy with even the smallest number that we can provide.
