Don't tell Esquire editor-in-chief David Granger that the concept of "magabrands"—magazines that have "extended" their "brands" to new media, old media and non-media"—is out-of-control bankrupt. Esquire North is the magazine's sprawling Harlem three-level condo on Central Park North; each room and everything in it was decorated by an Esquire advertiser. To have the honor of furnishing arcade seats in eel skin in the gaming room, both Kenneth Cole and Intel had to purchase at least one page (ooh!) of advertising. Last night all these brands threw a party for Riverkeeper. We don't care really about fisheries on the Hudson, but we do care about Robert F. Kennedy Jr., who is the main litigator for the environmental outfit. He is so boyishly handsome and so charismatic and so, well, Kennedy-like! Semi-socialite Melissa Berkelhammer stood alone near the panini bar as Kennedy gave a speech. And—was she wearing a sad pony mask?
