What are the pre-reqs for a Nobel Peace Prize?

As you probably heard, President Obama was awarded this year’s Nobel Peace Prize. According to the Nobel Prize website, the award was granted to him “for his extraordinary efforts to strengthen international diplomacy and cooperation between peoples.” Forget the right/left politics for a second, and just look at the schedule here. Per the Nobel Peace Prize Committee’s selection process

The Committee bases its assessment on nominations that must be postmarked no later than 1 February each year.
Bolding my emphasis. This means that Obama was nominated no more than 12 days after being inaugurated. Prior to his election, the only international exposure he had was the July 24th Berlin speech during his campaign. I honestly don’t see how any President would qualify within that time period. Am I the only one who finds this a little silly?
