The group that put this together has a show on BBC that I have yet to see. I find this video very entertaining to say the least. When recently asked what is 'Facebook" from an older relative this video permeated my thought process. "It's a place where people, you may have known in the past, can make defamatory statements about you or even blackmail you." - not entirely true, but something to think about before you accept your next friend.
I think this was very well made and does a great job of showing how different platforms make certain behaviors unacceptable and even rude.
