Foursquare and Narcisism
Like Twitter and Facebook, Foursquare taps into our inner exhibitionist self -- a malady of the post-Internet era. It allows everyone to be a Ruth Reichl, the legendary food critic -- an arbiter of taste. With a narcissistic quotient that is higher than a genius's IQ, it's only a matter of time before it's discovered by everyone from dithering fashion editors to pro athletes and pop stars. And when that happens, yet another tech pop phenomenon will be born.
