I'm only "scene" because I enjoy a lot of the music and I'm one of the only people on Earth who honestly enjoys the fashion. Overly flashy clothes, fucked up looking hair
(man I can't wait till I can afford fucking highlights), appropriating the concept of bling from hip-hop and the gender ambiguity Nigel mentioned. FUCK YES. Unfortunately, almost all of the people are enormous self-important douchebags, and I get more kicks out of trolling them on MySpace then I do trying to be part of their clique.
Also, for those who read too far into my making no immediate distinction between scene and emo, there is a HUGE difference. For one, scene music is everything ever smashed into one damn genre. Glam rock, pop-punk, hardcore punk, hip-hop, rave, FUCKING CHIPTUNES -- I've heard all of them together in one song before. I may have to grab an example at some point, because it's fucking great.
The fashion is mostly connected to emo by the hair. Everything else about it is, as with the music, every pop culture style from the early 80s onward being welded together into SOMETHING UNSPEAKABLE. Look at the linked picture above. IT IS EVERYTHING. All he's missing is cowboy boots and a damn trucker hat. Really. Oh, you want cybergoth too? Same guy.
How about stereotypical "metal"/"goth" fashion? There's a Dahvie Vanity pic for that.
(Dahvie is the unofficial leader of scene.) It's the best thing EVER.
The main thing that IS the same between emo and scene is the people. They're all whiny douchebags and many scene kids are the same ones who were in the emo crowd.
