From top answer:
“Blithe and potentially offensive generalizations coming:
•Palo Alto: rich people with kids, rich people who can afford expensive signs of consumption to show they care about sustainable living, Stanford faculty, has startups.
•Menlo Park/Atherton: rich people with kids and NIMBYists who care more about being rich than pretending to care about the environment, disgruntled Stanford professors, has few startups.
•Los Gatos: richer, has the nicest cars, has no startups.
•Mountain View: not so rich, has lots of startups.
•Belmont, Hillsborough, Burlingame, Redwood City, San Carlos: drive-through cities, few startups, have kids.
•Woodside/Portola Valley/Los Altos Hills: rich polo players. No startups, though some angel investors might live here.
•San Mateo: married couples splitting the commute, where one spouse works in SF, and the other works in San Jose. Some startups.
•Cupertino/Sunnyvale/Santa Clara: suburbia that is so heavily Asian it is causing white flight. H1B visa slaves live here.
•San Jose: tech companies, their employees, and all the other poor saps who were misled into thinking it was as cool as San Francisco, but cheaper.”
