Keith Olbermann, host of MSNBC's "Countdown," looks at the Wikipedia Scanner episode, in which a website made it vastly easier to trace edits made to the online encyclopedia back to the organizations that made them. He notes that two News Corp.-owned media properties — the Times of London and Fox News — reported on the scandal without noting their own, er, contributions to Wikipedia. Fair enough. But, then again, did Olbermann note any edits made by his colleagues at NBC?
