Many of my friends at work don’t use it. It seems that “joiners” are all for it but introverted types see social media sites as an intrusion.
In the eyes of government I’m definitely an introverted type because I do not trust them one iota. I’ve seen society change from the neighborhood constable who walked his beat and knew your dogs name to the cop in a car who is impatient if you ask for assistance and who will kill your dog on your front lawn if it barks at him.
