I read the Guardian piece on post-fact discourse. Although the author touches on this, I think they still have a big blind spot about the selective bias of mainstream media, by choosing what not to report. Take the shooting of black people by the police in the US; it's been going on for decades, but there was never a substantial article from a major newspaper about it until recently. I didn't hear about Michael Brown's murder from mainstream media, but it was all over my Twitter TL.

It's also a very limited historical view - an era in which that concept of journalism became dominant may be passing, but if we go back to the origins of the popular press, and particularly its massive expansion of influence in the 19th century, things look rather different.
