Don't be fooled by this sudden concern for truth, this is a fake epidemic of fake news, this is an attack on alternative media, google and facebook are already banning 'fake news' web sites from their advertising networks and there are calls for more to be done, you don't have to be a Philadelphia lawyer to work out where this is going..
It isn't an attack on "alternative" media. It's basic education. Before quoting a source and a story, read it first, and get a few other sources. Simple.
How often do people post links to stories that haven't been read first?
