Here are a few things I think of when I consider the values of the city that I have called home most of my life.
As exemplified by:

Educational opportunity

826 Valencia, Exploratorium

Innovation

Apple, Lucasfilm, need I go on?

Creativity

film arts foundation, artspan

Community service

Glide
Rainbow World Fund

Respect for diversity

Carnaval
Dignity for all Global Fund for Women, HRC

Spiritual Life

Grace Cathedral
Green Gulch Zen Center

Beauty

Golden Gate Park

Humor

real estate prices

Wit

SF Mime Troupe
Lively Debate Commonwealth Club

Respect for the Natural World

Earth Island Institute
Adventure Mavericks
Play! SF Bay to Breakers
Good Fun Hardly Strictly Bluegrass
Good Film SFIFF, German, Asian American, Gay and Lesbian, Silent, Latino, Human Rights

Good Food

Ferry Building Farmer's Market
Good Books City Lights
Really Good Coffee Peets, Blue Bottle
Most of all, this city values independent thinking and respects people who act bravely to protect the rights of their fellows, even at the risk of their own life or livelihood.

I (heart) San Francisco!
