Just my two cents: I thought it was just a great term for those of us who just don't feel like we "fit in" with the "norm".
I was HEAVY into New Wave in high school, and later got into industrial/goth. Both music scenes were a bit avant garde for their times, and my life evolved around the scenes. I didn't really relate to people that were into sports or movies or such. But for what it's worth, I still don't.
I haven't been part of any "scene" for years now. My life looks more akin to that of a soccer mom than a goth chick, but I still don't feel like I fit in with the soccer mom types. I grew up, but my tastes didn't.
