Anyone with an Internet service provider can be a pundit or whatever they want.

One of the most important disciplines in journalism is to challenge your working premises.

Twitter and Facebook are brilliant- tools, the journalistic uses of which are still being plumbed. They are great for disseminating interesting material. They are useful for gathering information, including from places that are inaccessible.

I'm convinced that the most important division in human affairs is probably not the one between left and right, liberal and conservative. It's the one between zealotry and understanding, between absolute conviction and compromise, between preachers and politicians.

Whether or not Twitter makes you stupid, it certainly makes some smart people sound stupid.

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

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