I think OP hit the nail on the head with the perception Hipsters create around what they do. It's this whole almost mystic world where they go out of their way to make others feel ignorant or like an "outsider". (i.e THIS IS OUR THING AND YOU CAN'T PLAY BECAUSE YOU'RE A SQUARE). And that sentiment was echoed in a lot of the comments below the post.

The irony is that they're essentially a community of outsiders, people who ostensibly have differing individual tastes but ultimately they are the mainstream they detest so much because they only exist inside their echo chamber. This is a pity because if it's true that hipsters have a level of discernment in terms of aesthetics that isn't inherent in most people, then they have the ability to become cultural pioneers and leaders, and by extension ensure the continued existence of their favourite fringe "thing" through mainstream profitability. Instead, they choose to isolate it from the mainstream and complain that no-one really supports it.

Anyway, great post. Really enjoyed reading it.
