@squinney,
												Yep, that was one of the observations I was going to make.  He did indeed look OLD.  (I watched the first 20 minutes or so.)  I was watching the audience-o-meter during those transitions -- when he'd go from the stool or whatever to the position he took for most of his response.  Even though he was talking, the meters stayed low.
Some other observations I made before I turned off the 'puter:
-  Format favors Obama I think. He's good at town halls... but nobody thinks he is. Lots of opportunities to look strong and physically vital next to McCain. And there won't be a cheering audience for McCain (so far as I can tell..?) which I think might discombulate him a bit (as compared to "real" Town Halls.)  [I said that here too, earlier.]
-  No cheering either though, good (Tom just said)
-  I think Obama being able to look right at questioners, respond to them, connect with them, that's good
-  wow the audience meter is way up there!! (CNN) [Obama was talking]
-  Yep, McCain looks creaky next to Obama
-  hmmm audience meter is high for mccain too -- men are noticeably lower though... and it's fading as I type
-  Interesting gender divergences with McCain... women like him more, men don't. maybe just has to do with that specific group (like one woman is a McCain supporter undercover 

 )
-  They do NOT like attacks. Audience meter went down on "Obama was the second-highest recipient of Fannie/ freddie money"
-  Oooh good answer here. Too professorial?  [that was when the young guy was asking how the bailout would affect his life, Obama answering]
-  ooooh rick davis, go Obama! [Obama responded to the Fannie/ Freddie thing by saying something about McCain's campaign manager]
Then I had to go.
