I'm sure this is totally different for various different people and different blocks, but over the course of 10 years living in 4 neighborhoods in SF (Soma, Mission, Inner Sunset, Inner Richmond) I never knew more than one neighbor along each street. I moved to Oakland 3 months ago to a very communal street and already know every person along our approx 25 house block. The lack of neighbor contact always seemed pretty ingrained in SF culture for whatever reason.
