You don’t have to be the best. You just have to be someone’s favorite.

For facebook it’s, yah know, someone’s favorite ubiquitous identity system.
I like the TrueFan theory. Some debate over whether it is 1000 true fans or 10000 sorta fans, etc.
Fun fact: in Japanese, you comma every 10^4, which makes a lot more sense to me as far as catching the eye and counting.. So 100B would be 10,0000,0000. A trillion is easy: 1,0000,0000,0000.
