Since Keith Olbermann's announcement that he was exiting his MSNBC show "Countdown," just about everyone has been speculating what his next move might be. Entertainment Weekly is reporting that Olbermann might be tapped to help Aaron Sorkin with a pilot script about a cable news show. Olbermann's job would be to write the rants, a source familiar with the project told EW. Olbermann has not commented publicly or tweeted about his break with MSNBC on Friday.
