There s one thing that s frightening about facebook, it's that it proves we re all the same, in our attempt to look original and different from each others. I see more and more people who look exactly the same, even if they come from a different city, state, country... have the exact same attitude, face, physique, one liners etc you know, shaved heads with goatees , skaters, emos, goths etc for men, and bimbo fake bitches , pseudo intelectual feminist boring girls for women.. I dont know if it's really that great to figure we re all basically copies of each others and following the exact same, limited amount of models. It somewhat means we re not all that usefull individually speaking as there are millions of others people exactly just like us and that they could replace us easily.
Back on topic; if you dont like facebook dont browse it and ... dont create an account... if you have an account on facebook it means you re just like every one else who created an account there.
Replying in reverse order from your post; not everyone is on Facebook for the same reason. For example, I have three grand children who live in Germany, Facebook is one of the ways we communicate with each other. As another example, my wife and I recently hosted a holiday luncheon for several retirement groups. One of those groups posted an invitation to the event on Facebook and others excepted or declined. I have a large and geographically diverse family. Many of us family members stay connected via Facebook. Facebook is not just a place for people to collect "friends" which are often other Facebook users they don't even know, you know?
Throughout time, many folks have sought to express their individuality by adopting certain unique styles or mannerisms. A few years ago, tattoos were edgy and not mainstream, for example. Today it seems there are more folks with tattoos then there are folks without them, making tattoos no longer unique or even that edgy. Someone (who was probably balding) shaved their head as a style solution which seemed unique. Perhaps it was Yule Brenner or me. Anyway, many guys, balding or not now shave their heads, making bald heads seem fairly common.
Teenagers frequently look for ways to make a statement which distances them from previous generations in some way. It was probably some teenager who first sagged his pants and now everyone, even middle aged men, is doing this. Not me though. I think it looks stupid. I feel for those who wish to be individualist. With so many folks in the world and the ease of communication, it has become increasing more difficult to actually be unique.
Really, in my opinion, one should just be themself and not worry about whether there are a million other people acting the sameway or doing the same things. For example, I like keeping my head buzz cut extremely short, which makes it appear to be shaved, for a number of practical reasons which have nothing to do with style. So long before it was "in style" I wore my hair this way and will probably continue to wear it so until I croak. Also, long before hoards of folks became obsessed with being healthy and looking fit, I was into fitness and bodybuilding. I am not about to change that just because it is in vogue now. I could go on about ways in which folks can be true to who they are, but it is simply all about being honest and having the confidence to be whoever you are whether it is popular or not.
