It's only been a couple days since Keith Olbermann announced he's the new chief news officer at Al Gore's cable channel Current Media, and already I'm hearing rumblings from within the struggling network that the ex-MSNBC'er has been told to chain up his considerable ego at the door.

"No doubt Al is very happy to have Keith join his network," one Current TV insider tells me. "Yet Keith is a double-edged sword. He'll attract a huge amount of media and viewers to the network, but let's be honest, he's a total pain in the ass to deal with."

I'm hearing the former VP has already given Keith the old 'Hey, you do know I'm the boss, right?' speech.
