Thanks to Flickr, we've seen four instances of some "I ♥ Anderson Cooper" graffiti over the past week. The marker mash notes at the 14th Street 1/2/3 station, outside the 66th Street 1 station, inside the 72nd Street 1/2/3 station, and outside the 72nd Street 1/2/3 station, on the newstand's NY Sun stand.

We've yet to investigate all subway stations along the 7th Avenue IRT (though we think we may have seen it at Times Square) so we're not sure how far this crush has spread.
