Aside from the demise of the careers of so many famous people, and not simply famous, but extremely talented people who might have contributed widely and deeply to our lives and culture, Social Media has been a disaster for truth and fact-checking. Once truth is thrown out you have anarchy. Now its more important to be popular and cool than boringly correct. Well known, rather talented people have torpedoed their careers through making some dumb emotionally driven, ill conceived rant or comment on SM, which is sad because the internet, as they say, is forever, and if you apologize and say you screwed up, well, that just makes you look weak and the trolls smell blood and go in for the kill. Rather unfair. but its good for business.
