I don't get this one. I would assume that you'd have to be extremely wealthy to be Steve Jobs's neighbor. As a result you'd think bumping into other extremely wealthy, successful people would be routine.
there's a mix of housing in Palo Alto - a fair amount of students and young persons intermingled with home owners of (very) expensive homes. I lived in a $1500/month place on Everett (cheap) and across the street there were million dollar houses, but a block in another direction were a few places that looked like 1920s era sharecroppers houses.
