What does your FB say about you?

Is my life the sum total of my facebook statuses and comments?
Is facebook the window to my life as the eye is the window to the soul?

In a day and age when we are so compartmentalized, individualistic, and private, what is it that we share in the social networking realms of cyberspace with these so called "friends"? 

Just 10 years ago, it was popular to hear that one could determine what another's priorities were simply by reviewing one's calendar and checkbook.  Now, I believe, it is no longer necessary to know another person well enough to have that kind of access.  In today's world of rapidly advancing mass personal communication (not just media), each person is pushing his or her own private agenda; whether conscious or no, you are constantly and definitively declaring what is most important to you post-by-post.

My life IS the sum total of my facebook statuses and comments.
Facebook IS the window to my life.

So, what DOES your FB say about you?
