The emo style I think evolved from a combination of punk and goth. 'Scene' is the new, hip style that has come out of emo, but without the sadness and depression.
The wikipedia article about emo made me laugh. "Early trends included straight, unparted hair (similar to that of Romulans and Vulcans in Star Trek)" Lolz
As for me, I was never part of any subculture. I used to go to a lot of punk shows in high school but I hardly dressed the part. Today I usually just wear whatever a girlfriend says looks good on me. I'm so lazy.
