People share everything on Facebook. That can be a very good thing or a very noisy thing. With Foursquare, people know that they're getting information specifically about a place, advice about where they are and what they could be doing. It's a very filtered view of the world.
Don't let anyone tell you your ideas are stupid or the thing you feel most passionate about 'won't work' - it's happened to me time and time again, and we find that if you push at what you think is interesting hard enough, you're probably right.
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.
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.
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.
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.
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.
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.
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.
Asking Siri where the nearest sushi bar is - that's not interesting. What's interesting is asking your phone where one of your friends have last had dinner in the neighborhood, or having it recommend a cool paella place in Barcelona because it knows you eat paella all the time at home.
The misconception about Foursquare is that it's just hipsters in New York and San Francisco checking in at bars. It's happening all over the world. I've seen huge growth in Europe, Japan, South America.
