It's a class thing more than a geography thing. Culturally working-class urban Americans are chatty in almost every American city, save the most recently-urbanized ones (like PHX -- and even there there Latinos are chatty even if whitey ain't...)

Reading a bunch of these posts, a similar thought occurred to me. When I lived for a short time in Manhattan, I found the friendliest / most chatty were always working class types that ran small businesses or worked in the trades. I wonder if it is nothing more than these people are much more exposed to "strangers" through their professions. As a result, they are much less afraid to open a conversation.
