Look, imagine two tungsten balls, 4" in diameter each, at night. One is painted matte black and the other is heated to 2500 degrees Celsius. Which one is more visible? These are two absolutely equal balls and one constitutes exactly 50% of the population :-)

I take Caltrain regularly (I live on Peninsula and work in SF FiDi) and I see these people, but nothing out of ordinary. There're, I believe, 8000 working in FB Menlo Park office. That's a lot of people. And the industry is heated up, so these people are more visible because the temperature is higher. So what, it happened before (2001) and will happen again :-)
