...particularly with respect to the use of technology, taste in music, movies etc.
I have seen my share of people like this who like to go "alternative" just to set themselves apart and I would like to know if there's a word for them? I wouldn't mind a casual/Internet-born word either. Just need a term I can label them with in my book. :)
EDIT: I am looking for a word that's disapproving in nature. :)
EDIT 2: I am actually looking for a term that signifies "fake" in more particular terms with this scenario. Think about the people that only use Linux, only listen to Death Metal, only watch cult movies with the sole motive of being NOT mainstream. I am sorry that I didn't made myself clear enough.
