The basic rules of flag design include:

• Keep it simple.
• Use meaningful symbolism.
• Use two to three basic colors.
• Don't use lettering or seals (too hard to read from the ground when the flag is atop a pole).
• Be distinctive.

I live in Alameda, California. Based on these rules, our flag is well designed.

San Francisco, on the other hand, was specifically called out as having a bad flag design in the TED Talk. Here's how Autodesk is pitching in to help out.
