Nerds and rich people.

It's what you need to make the next Silicon Valley. How do you get nerds and rich people in the same place? When do rich people want to live in a place that nerds like? And what do nerds like?

What nerds like is the kind of town where people walk around smiling. This excludes LA, where no one walks at all, and also New York, where people walk, but not smiling. When I was in grad school in Boston, a friend came to visit from New York. On the subway back from the airport she asked "Why is everyone smiling?" I looked and they weren't smiling. They just looked like they were compared to the facial expressions she was used to.
