Ever read that book "The Tipping Point" by Malcolm Gladwell? It explains how evolving, collective social preferences build up a nascent trend to that moment--the tipping point--when it reaches critical mass, goes super nova and becomes unavoidably visible, like trucker hats a couple of years ago or Starbucks in the 1990's. When this detour sign was originally (and overwhelmingly) "sticker bombed," the New York City Dept. of Transportation took a clever and easy way out: They simply covered up the old sign with a new sign. Problem solved ... or so they thought. Like on the sign underneath, a few stickers appeared gradually on the new sign, then in a sudden burst the orange board got bombed like crazy. Message to the NYC DOT? Resistance is futile. By the way, the detour sign stood at the intersection of Houston and Allen streets in Manhattan. It has since been taken down.
