I feel lucky because earlier in my career, I found what I liked to do; it's build software that you see your friends using on the street, and they like it. ”

Forget about where you want to be and go out and build stuff. Dodgeball came from being bored at work... things happen because you make them happen. Stop sketching, and start building. ”

You know when people leave a job, and they say they didn't know what they came away with after two years? That's how I felt when I first left Google. ”

I didn't really start building my own stuff until I was 24, 25 or so, and even then, I ran into a lot of resistance from, like, older folks, like my bosses at other companies or people in the industry that were like, 'Oh that's an interesting idea, but it will never work.' And, I don't know, I kind of believed everything that they told me. ”

It's very clear to users, more clear than in other apps, that Foursquare is an app for search and discovery, and we're very good at delivering you a social map that will show you friends' faces on the map and things that you might like. ”

It's difficult to build services that are supposed to scale to, you know, 30, 50, 100 million users right off the bat because they got to be kind of tailored down; by definition, they have to be a little bit generic to speak to that large of an audience. ”

My buddies are like, 'You live the most amazing life!' Well, I'm working like a dog. I come home most nights and pass out on the couch. ”

We've got over 1 million merchants who have claimed their businesses on Foursquare, running specials and doing other things. What we want to do is take these tools used by the 50-100 national retailers and make them accessible to our 1 million merchants. Then you've got something really powerful. ”

I'm obsessed with the idea of social TV. ”

Between the three, Facebook is literally everyone I've ever shaken hands with at a conference or kissed on the cheek at Easter. Twitter seems to be everyone I am entertained by or I wish to meet some day. Foursquare seems to be everyone I run into on a regular basis. All three of those social graphs are powerful in their own. ”
