That article doesn't actually explain what a hipster is at all. I suspect because it's a catch all phrase, without a clear definition - and therefore used to disparage whoever one wants to disparage. There are all sort of vague references to characteristics of 'The Hipster', but which don't seem to have any coherence as far as I can tell. To suggest that the rave generation weren't silly in there fashions, or often apathetic in their politics, (but today's youth are), is nonsense. So what do you mean by a 'hipster'?
