I've become one.

I work in Greenpoint Brooklyn, the Mecca of the Hipsters. It's a place with a bike tied to every street sign, fence, pole, or factory. Walk a block and you'll see 10-20 vintage bikes. It's like a bike time zone, or museum, where Schwinns of all flavors reign supreme and where old Fujis and Motobecanes are king. I learn alot just walking the streets there and looking, and hence, I've become abit of a snob. I've learned what to look for and what is quality and what is not.

Unfortunately, your basic hipster doesn't care what a bike looks like, actually the more scratches, the better they seem to like them, so it can be a disheartening experience....
