Obama's Speech Surprise

What did everyone think of Obama's decision to pop into the Pepsi Center at the end of Biden's speech last night?

I watched this happen at a crowded restaurant in Denver, full of Democratic convention-goers and they were surprised, but I don't think in a good way. After all, isn't the WHOLE point of waiting hours and hours to get into Invesco field tonight for Obama's speech to see him come out for the first time during the whole convention?

"No more suspense," I overheard someone say. I agree.
