Of course I also noticed the repeated cheering of "O-bahm-mah" over and over. It really got me to thinking about how perfect of a name he really has for the crowd to chant incessantly. Just kind of one of those lil "That's interesting" things I noticed.
As a final note, more on par with the inauguration, the New York Times had a blog post about the actual inauguration itself. In it they mention the rather botched nervousness possessed by President Obama and Chief Justice John Roberts. I guess, although mostly to Chief Justice Roberts' blame, President Obama never recited the actual oath as recorded in the Constitution. I guess there's some "Lame Duck" Amendment or something that supposedly automatically transfers power, but according to the original Constitution, I'm not sure he's actually president. Of course then I'm not sure who is.
UPDATE: Obama redid the oath. Case closed.
UPDATE PART TWO: Biden takes a shot at John Roberts for messing up on the oath.
UPDATE PART THREE: The oath was performed the second time without a Bible. Guess that might make some of the people that didn't like the idea of it happy.
UPDATE PART FOUR: Some media backlash occurred because of rather limited access for the redo of the oath. I don't think is going to be too big of a deal though.
UPDATE ON YO-YO MA: So apparently the quartet didn't actually play the music live, it was prerecorded.
