Well, first off, you have to ask yourself - who and what is a hipster? Because people tend to look at things very subjectively. Once you answer that question to yourself you may be able to understand a bit further what the deal is.
If you are not able to think on your own, I can kindly refer you a very nice site: www.google.com
Here you can find a lot about hipsters.
If you are really slow and cannot use mentioned site, I can assist you with some answers - if the questions are right.
