The Bay Citizen — the new nonprofit news website financed by neighborhood investor and philanthropist Warren Hellman — launched today. Its lead story focuses on the wildly varying property taxes paid by the owners of the mansions on Outer Broadway.

Included is an interactive graphic that is something of a star map to Pacific Heights, describing who lives where and offering a bit of history about some of the finer homes in the neighborhood.
