Subculture that Interests Me

One subculture that we have not talked about at all, but is very prominent in contemporary culture today is the hipster culture. There are greatly talked about and recognized in today's society, although I know they rose up during the 1940's and 50's after WWII. To my understanding they are rather rebellious, anti-conformist young adults with a particular clothing style not alluding to mainstream fashion. I also conclude that they listen to jazz and more modern types of unique and mellow music, and seem in general to have a more laid-back and liberal attitude. I am not well-versed on the ins and outs of their full culture and style, but they interest me very much in that I would like to know more about how they started and what their more specific qualities are that make them esentially "hipster". They are especially interesting in that they are so popular today, especially in the college scene, so I can get a small taste of the hipster style just by first glance. They seem mysterious and I feel that there are many people who are posers of this subculture that try to dress and act in that way. However, I am curious as to what qualities one must have or behaviors you must follow that make you a true hipster.
