I don't like McInerney, and I don't particularly like this article, The Death of (the Idea of) the Upper East Side -- New York Magazine, except that it articulates my long-held fears that I won't ever live in Manhattan again.
This MetaFilter quote struck home with me:
"Manhattan is the new Upper East Side; Park Slope is the new Village; Queens is the new Brooklyn; and the Bronx is the new Queens."
