Mashable: Remember that time a couple of Norwegian 20 year-olds posted a picture to Facebook? Sure you do. The one where the girl, Catherine, agreed to have sex with her friend Peter if the picture got a million Likes?
It turned out to be a joke for the benefit of the pair's friends. Still, the picture zoomed past a million Likes in less than a day. Now the story has become a subject of an academic white paper by a trio of Facebook data scientists. The paper investigates how this picture, along with a similarly viral posting from President Obama, made the big time.
