You're building a tool, not a piece of art. Don't be blinded by the vision.

If you don't have those moments where you go too far, then you're probably not going far enough.

Once you have something so deeply infused in your culture and your brand, it would be very difficult to reverse that inertia if you wanted to.

It takes some experimentation to figure out what people like and don't like.

I'm just not used to talking that much about myself. It feels strange.

I just like to build things and do things.

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.
