Andy Ihnatko on why the term “Mainstream Media” is meaningless:

You waste your shot by blaming it on The Mainstream Media instead. When I get to the end of your heroic screed I’m tempted to click the “Comment On This Post” button and ask you to explain what role, precisely, the Kansas City Star played in this hypocrisy and how they benefitted.
“Oh, all those Mainstream Media organizations behave the same way,” you counter. Ah. Is that why you won’t rent an apartment to one?
Again I say: it’s a meaningless term. Look at the state of publishing today. Does this look like an industry that’s good at working together on any kind of a common agenda?

Well worth a read, whatever side of the discussion you perceive yourself as supporting.
