Why don't the Nobel people just wait until you've been successfully informed before telling anyone else? Where does this self-imposed deadline come from?
I don't think a Nobel recipient is going to spill the beans on the announcement.
Maybe they shouldn't have done that before checking if the person was ok with being awarded the prize?
But they clearly want to tell them, so why are they trying to do it in the middle of the night in a hurry rather than doing it calmly?
Why this self-imposed rush?
They could pick a slot that's during the day in the US, but then it'd be night for someone else. What justifies the US importance to make such a change? Using the timezone of the committee as they do now seems as reasonable a compromise as any...
