Read part 1, where we look at Google’s plan to reinvent the office park, and part 2, where we explore why all office parks look the same.

A friend who lives just a few blocks away from me in San Francisco’s Mission District used to work for one of the tech companies in Silicon Valley. Each day she would get up and walk to 24th Street and Valencia to join the long line of tech workers that forms there every morning.

The major tech buses use the same stops as the city buses, but the passengers are different. She was used to the city buses, where the crowd skewed very young and very old and more than a little crazy. In the tech bus line, no one looked younger than 20 or older than 40. Almost everyone was male. No one was visibly in the middle of a schizophrenic meltdown. On a city bus, odds were high that someone would be singing “Broken Wings” by Mr. Mister at full volume in the seat behind you. On the tech buses, the only sound was the clicking of laptop keys.
