I remember the video nasties of the 90s were 'far from imaginary dangers' for kids, before that it was rock music that the data was screaming at us about. Maybe social media does hold an actual danger this time, but we are a hysterical bunch of knee-jerk reactionary nutjobs, when it comes to new things and kids.

I wouldn't be surprised if 20 years from now we see social media as just another hysterical reaction that generated a generation of bad law, wrecking, or diminishing a number of lives, for no good reason at all.
