Yes, IMHO this should be the goal. Coupled with directly elected European leaders. This election campaign would be a hit. Of course,... writing a post is easy. Getting this done requires a political genius.
What I like about this specific easter egg is how they solved the issue with religious holidays: Only those that care about <your religious holiday here> get to see the message.
This is a very brave step in the right direction. In the long run they can NOT justify to give those remote learners not a "real" MIT degree (and I am sure they know this).
