Late 80s (I think), Sports Illustrated did a behind-the-scenes expose of ESPN when the network was taking off. A description of Olbermann was not flattering, and the article implied that his colleagues didn’t much care for him. He fussed over his hair, and methodically applied makeup before every appearance.
After he left ESPN and went to network news, he complained in an article how difficult it was to do actual journalism. The hours it took to research something, verify it, re-verify it. Much different than running down the scores. Obviously, he considered this to be too much work, and he’s now doing what he does best: BS’ing.
Another Freeper posting said that he posts and read the Daily Kos while on the air. Many of his comments come right off the computer screen.
