Long ago, “friend” was a noun and “city” was a location: Santa Fe, at the weary end of the Santa Fe Trail, from which dusty travelers launched the ambitious start of cultural tourism some 75 years ago. Then, last decade, new monikers began cropping up concerning cities. Who’s Your City?, a book written by socio-urbanist Richard Florida (of Toronto), unpacked his thesis of a “creative class” dominating global cities—workers in so-called creative professions, from art to film to physics, localizing effects of tolerance and self-expression to seed new-society economies.
