Just want to chime in, it looks like Obama is heading out[1] after answering only ten questions. I think it's fair to call that disappointing when the thread had more than 12,000 comments.
Is it? It appears that his AMA was online for maybe 45 minutes. How long should we expect the President of the United States to stay on the site for? Presumably has has other things to do.
1. Space Race
2. Internet Freedom
3. Favorite Basketball Player
4. Small-Business tax breaks
5. First Activity on Nov 7
6. Most Difficult Decision
7. Money in Politics
8. White House Beer Recipe
9. Jobs
10. Work/Life Balance
They are largely boilerplate answers to softball questions. Nothing you couldn't get from listening to a White House press conference.
Questions about the state of Iraq, Syria, Libya, Iran, Egypt, et al would have been more interesting. Characterizing sending more troops as a hard decision is not too surprising.
Ok, but all you're gonna get from him on foreign relations ESPECIALLY is the exact boilerplate that comes out of the state department. There are actually policy reasons to stay boilerplate on that stuff, above and beyond political considerations.
That said, he did come about as close as he could to acknowledging the surge in Afghanistan didn't accomplish much. And he called for a constitutional amendment on Citizen's United, which he apparently hadn't done in public before (according to news outlets trumpeting it).
That's 3 minutes per question, given the half hour he allotted. I don't think that's too disappointing. Did you really expect him to answer 12,000 questions?
For perspective: I read a bit in the most recent New Yorker describing a fund-raiser dinner with the president; it was $50,000 a plate and the president had one hour which equated to 1 minute per person. His staff knew he wouldn't have time to eat so he was prepared a meal he ate quickly in the kitchen beforehand. A staffer with a watch would tap him on the shoulder every 5 minutes when he needed to move onto the next table.
