San Francisco is not beautiful. There are nice residential parts, and it isn't a boring place, and there are lots of great technology companies. But this city is not beautiful. Have a walk around the civic center if you doubt.

I disagree. There are parts of the city that are terrible, but there's so much that's lovely, and the physical environment is almost peerless. Corona Heights park; Glen Park canyon; Ocean Beach; the Embarcadero; Holly Park in Bernal Heights -- gorgeous.

Unfortunately mostly what I see is feces on the pavements, noise, litter and bad smells and whole lot of unhappy grumpy people making their way.
