Casual reliance on unnamed sources...corrodes our credibility and, in cases that are rare but not rare enough, may abet journalistic malpractice.

Beating up on the so-called elite media has a nice populist ring to it.

Julian Assange, the WikiLeaks founder, has on several occasions talked about transparency as an absolute principle. I don't personally believe that.

The most obvious drawback of social media is that they are aggressive distractions.

The queen of aggregation is, of course, Arianna Huffington, who has discovered that if you take celebrity gossip, adorable kitten videos, posts from unpaid bloggers and news reports from other publications, array them on your website and add a left-wing soundtrack, millions of people will come.

I don't think anyone at Fox believes they are producing even-handed, impartial coverage.

My view of social media is that it is a set of tools, not a religion.
