This is from the adbusters website describing what they're about:
"We are a global network of culture jammers and creatives working to change the way information flows, the way corporations wield power, and the way meaning is produced in our society"
That made me chuckle. They could have just as easily said "we're a bunch of loud mouths with a bloated sense of self-importance that no one can stand listening to so we mostly shout at one another and pretend we're being heard".
You know one way to establish significance is to try and portray another group as being insignificant. Insightful this article was not.
And on the "hipster" angle, I'm old enough to be the father of most hipsters so I don't qualify as being one.
