AP - Feb 14 - Two people who are about to enter a relationship share an average of 1.67 posts per day. Then, their FB interactions start to decline, presumably because they are spending more time together offline. Facebook data scientist Mike Develin, whose background is in mathematics, notes that the relationship stuff is a side project. Someday, researchers studying FB data may be able to predict whether a couple will break up, learn whether people are happy together or see what makes relationships last.
