Who am I ?

The answer to the fundamental identity question, "who am I?" can be given only in relation to the others that we interact with. And the answer to this question seems clearer after we take a look at our list of social network friends. On social networking sites we produce content by indirectly answering the question "who am I?". We organize our own and are recognized as virtual identities. Facebook represents real people through a specific element: the profile picture. This picture, more often than not shows a face, and a smiling one at that. In fact our face is our most private space and simultaneously the most exposed one. How many people are allowed to touch our face, for example? Generally speaking, the face is also one of the major points of reference we have in the world. There are even "special" regions of the human brain, such as the fusiform face area (FFA), which may have become specialized at facial recognition. Faces are now so exposed that they do not remain private, but are thrust into the public domain and shared (they can even be "tagged" by other people).
