Are bloggers and pundits crossing the line to editorializing with their biased questions, interpretative news and public advocacy? Or are they adding the kind of texture and depth to the news that unbiased writers can’t offer? Is a pundit a journalist, or do pundits give journalists a bad name? What exactly qualifies one to be a journalist or a pundit? What does a journalist do that’s different from a pundit and vice versa? Is Stephen Colbert a journalist or a pundit? What about Seth Meyers? John Oliver? Trevor Noah? What were Jon Stewart, Chris Matthews, Larry King and Lou Dobbs? Please answer with a substantive response!
