I silently deleted my facebook account about two years ago because I didn't like losing my time looking at stupid stuff. I found out that falling into the Facebook time vortex was too much of an inconvenience and the only way around that was to delete Facebook. Now when I say that I don't have a Facebook people ask me what's wrong with me, if I have things to hide and plain and simple tell me that I'm some kind of social pariah...
What bugs me the most is that people are judging me before even hearing my concerns about time wasting, privacy. Facebook has become a token of having a social life.
I am not saying you all should delete your Facebook, that's a matter of personal choice but people should think about what they add to the "standards" of life. In my books Facebook should really not be in the standards.
