Subcultures, past and how they're not so present anymore.

Subcultures. Every decade before 2000 consisted of multiple cultures, categorising people and depicting personality. Was this as right as everybody makes it out to be? I guess it couldn't be helped. In a world before technology, before you could pick up your phone and text your friend when you're feeling lonely or bored, there needed to be a sense of belonging amongst people. Subcultures were like a really strong bonded friendship group, everyone has the same kind of views and dress sense, and you stick together.
You had punks, skinheads, rockers, bikers, teenagers, teddy boys, all evolving from one to another throughout the years. Still today we see remnants of different subcultures through the clothes we wear and the views we have, but Subcultures just aren't as dominant now, and the reason for that must be because we as humans have evolved and adapted, we no longer need a group of people 'on our side' to get by. We are more independent and individual, if we want to make friends we can go on facebook, if we have an opinion we can tweet about it.
I'm not going to say we have changed for the better, in a way it's pretty sad that we no longer rely as strongly on the people around us to get by, instead we rely on the model of phone/laptop/whatever we have in front of us, or how many followers we have on social networking.
