This article makes me tired. But it's about us, so... Here ya go:
The hipster haunts every city street and university town. Manifesting a nostalgia for times he never lived himself, this contemporary urban harlequin appropriates outmoded fashions (the mustache, the tiny shorts), mechanisms (fixed-gear bicycles, portable record players) and hobbies (home brewing, playing trombone). He harvests awkwardness and self-consciousness. Before he makes any choice, he has proceeded through several stages of self-scrutiny. The hipster is a scholar of social forms, a student of cool. He studies relentlessly, foraging for what has yet to be found by the mainstream. He is a walking citation; his clothes refer to much more than themselves. He tries to negotiate the age-old problem of individuality, not with concepts, but with material things.
He is an easy target for mockery. However, scoffing at the hipster is only a diluted form of his own affliction. He is merely a symptom and the most extreme manifestation of ironic living. For many Americans born in the 1980s and 1990s — members of Generation Y, or Millennials — particularly middle-class Caucasians, irony is the primary mode with which daily life is dealt. One need only dwell in public space, virtual or concrete, to see how pervasive this phenomenon has become. Advertising, politics, fashion, television: almost every category of contemporary reality exhibits this will to irony.

I don't disagree that it's totally bizarre to see 21-year-olds dressed like my mom did in the '80s—or that there is a '90s-themed dance club in Portland now—but this does not mean that young people are less authentic than you were when you were a kid. Just that it's their turn to be young and dumb.
