Facebook is about sharing experiences that you've had. Foursquare is more about the present tense and the future tense.
People used to pooh-pooh the idea of a check-in, saying that this wasn't interesting. But when you have 3 billion of those data points, you can take any latitude and longitude anywhere in the world, and I'll tell you what is interesting now, 20 minutes from now, and 6 hours from now.
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.
My mindset is of the person who is still unsure whether they have enough money in their ATM to go to another bar. I lived that way when I was unemployed, when I was a snowboard instructor, and when I was at NYU. A lot of my personality is stuck in those five years, and I don't know if that's ever gonna change.
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.
