Groupon has some interesting assets.

Mobile is something I think about all the time now.

I think daily deals are a good idea. Any ad people view as content is a good ad, and that's true for daily-deal ads too.

The same regions of the brain light up when someone touches their smartphone as when they touch a family member or a pet.

I am very aware that I'm one of the luckiest people who ever lived.

One of the torturous things about my job is that, as time goes on, you get more and more clarity on all the things you've screwed up and all the mistakes you've made.

I think mobile advertising is going to be huge.
