If there's something you want to build, but the tech isn't there yet, just find the closest possible way to make it happen.

One of the biggest hurdles about Foursquare is you need to remember to use it.

I used to snowboard 30 days a year. Now its down to eight.

I'm obsessed with the idea of social TV.

Don't let other people distract what you're doing. There's always haters.

I keep a notebook in my pocket, and I write down all the stuff we could ever do with Foursquare.

I'm still a really shitty programmer, but I know enough to hack a prototype together.
