From Noel Sheppard at Newsbusters comes the news that less than 48 hours after urging Daily Kos readers to dig up all the dirt they could on Fox News host Glenn Beck, Keith Olbermann has changed his mind:

The previous update: to clarify something I obviously didn't previously, I'm not talking about letting up on criticism of Lonesome Rhodes' work here. I am talking about calling off the Baker Street Irregulars - while reserving the right to reactivate them. Trust me, I'm going after him tonight on the tweet to his masses that precipitated this, the "find out everything you can" about three Obama appointees.

Hustler Magazine's Larry Flynt offered a million dollars to anyone who could prove a GOP congressman had an extramarital affair. Olbermann's call to find similar compromising information on Beck has been squashed, probably because Olbermann's bosses didn't want one of their employees to ape the tactics of a pornographer.

Or perhaps he was shamed into dropping it by David Carr who blogs at the Nirvanna of liberal media the New York Times:

While Mr. Beck may be serving as a proxy for the party of opposition, his targets are members of the administration, a rugged game to be sure, but not one that attempts to investigate journalists and commentators for having contrary opinions. What might Mr. Olbermann do if someone digs up dirt on his intended targets, who, like him, work in the infotainment industry and have been elected by no one? Once the game of oppo research on the press begins, it's hard to tell where it might stop, no?

Oh my. When the sainted New York Times tells you you're off base, what's a liberal media snot like Olbermann to do?

Actually, I think it more likely that Olbermann's bosses didn't want to get in an "outing" game with Glenn Beck. God knows what Beck's minions would dig up on Olbermann. And his bosses.
