Missing Out or Saving Myself

Within the society that I live, there are many different forms of communication and ways of interaction. The handwritten letter is one that everyone really loves and when you open the mail to find a personally addressed envelope, you are thrilled. But it pretty much stays at a novelty and many people don't take the time to actually use this method. The telephone has been around for quite some time, but as the years progress, I find that it is used less frequently. Email, can be argued as being the most common and the standard form of communication across generations. Online chatting has become quite popular as well but is not used by all. It kinda stays between the younger folks, and as you get older, using Messenger, Google Talk and the like is not as common. Skype is another more recent form of communication where you are able to talk, as though on the telephone, but through your computer. This is a nifty way of communication that is cheap and relatively painless. Text messaging is predominant and though everyone and their dog has a cell phone, they are not used for actual talking as much as "texting" your "fav. five". And then there is this: "a social utility that connects you with the people around you." Any guesses for what this can be? Facebook!
Facebook is a way of networking and communicating with people from your past, your present and I wouldn't doubt, your future. This phenomenon started in 2004 and was originally only available to college/university students with a campus email address. Since September 2006, this utility was opened up to be used by anyone with an email address and by July 2007, it had 34 million active members and was the seventh most visited site in the United States.* Though it started with the university crowd, this network has spread throughout high schools, families, parents and work places.
Many friends of mine are proud members of this network and beckon me to join in with this social gathering. They tell me all the great advantages of "having Facebook" and are constantly making me feel as though I'm missing out because I'm not connected. For some, Facebook has become their principal way of communication and they rely on it fully to get messages to each other, plan events, to stay up to date on the latest greatest, know the person's dating status, to find new friends, to stay connected with childhood playmates and to watch and observe the lives of others through videos, pictures and stories. Discussions are had, comments are made, and the world is aware of every move that you make. You are comfortably distant, yet jarringly vulnerable.
My opinions for Facebook are strictly observational considering I have not become a member, and the debate of whether or not I should, is continually being presented to me. I question what this social utility says about the society that I live in. How has our culture come to a place where virtual connectivity is the norm and if you don't take part, you are on the outside, the outskirts, an outliers? How as it happen that suddenly we are willing to expose our every move to the world, let them know who our top friends are, and rekindle friendships that never existed? As one that hasn't taken the plunge and entered this virtual world, am I truly missing out like my friends say, or am I saving myself from a reliance on a computer to connect me to the "people around me"? Has our society come to a place where physical interaction is no longer needed, and we are able to be sustained and fulfilled within our cyber-world? How long can I stay on the outside and still remain on the inside of society? Will I have to cave to fully know how my society works, or can I just observe and look objectively from the outskirts? Am I missing out, or am I saving myself?
