MSNBC seems to work very hard to maintain its dead last place in the cable news ratings with on-air non-personalities like Keith Olbermann. It's hard to imagine a business that so clueless that it would waste precious advertising dollars on a network that is consistently the loser in virtually every time slot.
What is their latest ratings? I did take note a couple of months ago that once he really went all out being an a$$ (more than he was) that Olberman's ratings crept above Matthews and Scarborough. My theory is he took that as license to really up the ante.
