Faux-anthrax victim now a "cultural earthquake" - that's a good thing, right?

Keith Olbermann just needed to find his voice. He'd been a droll sportscaster, a serious news anchor and a bickering critic of Fox News host Bill O'Reilly. But none of those personas really clicked.

Then he found one. A little over a year ago, as the White House fumbled and botched the Hurricane Katrina recovery, Olbermann finally blew up.

He concluded a broadcast of his MSNBC cable news show, "Countdown," with an indignant rant in the rat-a-tat-tat cadence of his idol, Edward R. Murrow. He called it a "Special Comment."

And just like that, Olbermann found his voice -- the angry everyman. He became a liberal counterpoint to conservative media ranters like O'Reilly and Rush Limbaugh, and an Internet star, too.

The result has been a cultural earthquake. sfgate.com via Crooks and Liars
