I should have linked to this MediaShift Q&A with Brian Williams days ago. The NBC Nightly News anchor has some fascinating things to say, including this: "We throw more knowledge away during a given day than the sum total of what we put on the air."

That's partly why Williams' blog, The Daily Nightly, is a group venture, he says. "I just got out of a planning meeting for the 9/11 five-year anniversary, and the big part of this meeting was, look, we are format-limited. We only have 30 minutes for all these broadcasts we're talking about, we’re going to do some really in-depth reporting on the 9/11 anniversary. Are we safer? Are we better off? Where are they now? We're going to have a huge online component. We're going to devote a lot of airtime to telling people 'please read more of our reporting online.' That's our reality."
