San Francisco The Snobbiest City?

Travel and Leisure Magazine has published a snobby city list and San Francisco was voted number one. I am not sure exactly what their criteria was but they claim that the always popular tourist destination to be the snobbiest in the nation. San Francisco was followed by New York as number two, Boston as number three and Minneapolis/St. Paul and Santa Fe as four and five.
Having lived in three of the top five cities I was rather surprised. I guess I must be a snob too! I just like to think I'm just better than everyone else!
