Keith Olbermann -- what's the deal?

Here's Keith Olbermann in a long but worthwhile clip.

I'm not sure when Olbermann completed the transition from humorous SportsCenter anchor to the new Edward R. Murrow, but he seems to be pulling it off rather well.

His piece on the 5th anniversary of 9/11 was fantastic. The best point from that one was about ground zero. I don't have the link, but he said something to the effect of how it's been 5 years and the WTC site is still just a hole whereas months after the battle at Gettysburg, Lincoln himself was there to commemorate the memorial. And that was the 1860's. 5 years later, there's no memorial, there's no new building, just a hole.
