I think the notion of traditional anchor is fading away - the all-knowing, all-seeing person who speaks from on high. I don't think the audience really buys that anymore. As a viewer, I know I don't buy it.
I tend to relate more to people on television who are just themselves, for good or for bad, than I do to someone who I believe is putting on some sort of persona. The anchorman on 'The Simpsons' is a reasonable facsimile of some anchors who have that problem.
The world reacts very strangely to people they see on TV, and I can begin to understand how anchor monsters are made. If you're not careful, you can become used to being treated as though you're special and begin to expect it. For a reporter, that's the kiss of death.
