I noticed that the [favorite users](http://mathoverflow.net/users?tab=favorite) tab on the main user page is filled with people from StackOverflow, rather than MathOverflow. It is also the same on the [math.SE favorite users](http://math.stackexchange.com/users?tab=favorite) tab. 

Is this the first step of the programmer's plan to take over the world? I guess, first, they become the favorite popular clique on all stackexchange sites, and then....?

Or perhaps this is a Winter Bash thing?
