I hope this works..?!

This interested me because Facebook's requirement user age is thirteen years old but have no true way of knowing if thats correct. A kid of any age can access Facebook if they have the knowledge on how to create one. Adults hardly grasp the concept that what they post could possibly have consequence later so young children cannot be aware or responsible of how 'public' they have made their lives till they are old enough to be held accountable. Facebook has become not only a social network but an informant and a regulator of the economy. How young is too young to receive and process this information? Why does it matter?
