Although their survey only covers cities with more than a half million population, RIS Media has put together a list that includes a few surprises:
Four of the top ten markets are in California (San Francisco, San Jose, LA, and San Diego). And 7 of the top 15 (almost half the list) are on the west coast of North America.
San Francisco and Manhattan are neck-and-neck.
Two Canadian cities (Vancouver and Toronto) made the list.
