I've seen that link, there is poop on some of the streets, just like every major city in the world. I saw it in Moscow in the 80's, Stockholm, Paris, even Singapore (the cleanest city I've been to). They have that problem in Boise and Fargo and Wichita.
Why are you so fascinated with the problem in San Francisco?
