Yeah, I was gonna say the same thing as the last post. When I go to Starbucks, it's mostly soccer moms and office workers. Hipsters go to places that are way more pretentious, usually independent, and often use unusual methods of grinding, roasting, or brewing their coffee.
It's not the commonly accepted definition, but in my mind, a hipster is somebody whose life revolves around constantly keeping up with the newest trend of the "hipster" subculture, and looking down on anybody who doesn't follow those trends. There's sort of a hipster trickle down effect, too, with the most extreme versions of the trends being started by people in LA, SF, NYC, Seattle, Dallas, etc, involving products made by small manufacturers or even homemade, and then those trends work their way out of those areas, get produced in "watered down" form by major manufacturers, and are eventually adopted a few years later by people in less "hip" cities. Fixed Gear bicycles are a good example, they first became popular in the SF Bay Area a few years ago, and were generally built by enthusiasts from parts, then they were picked up by a few small manufacturers and spread to other progressive metro areas, and now they're being sold at Wal-Mart and you see them all over the country.
