Any sub-culture or fashionable bandwagon which can be labelled via name isn't worthy of lasting discussion, since it will fal out of fashion as quick as it came into it. I only recently heard of "emo".
The only sub-culture I belong to is the teenage one, which thankfully never dies. Anything else is just a sign of insecurity.
Mad Johnny, I admire your geographical anonymity; but your comments on the underdevelopment of American teenagers isn't exclusive to that country; alas, it is happening the world over.
