Summary
This paper presents novel findings about how the action "liking a Page" difuse in the Facebook social network. The authors analyzed all the Facebook Pages created between Feb 19, 2008 and Aug 19, 2008, and calculated the length of the "like chain" and the "initiator" vs "follower" demographics of a Page. They also developed a novel way of predicting the maximum length of a "like chain" using zero-inflated negative binomial regression.
Discussion
The authors clustered the fans of certain Facebook Page by connectivity (there's a friend path between any two fans in the same cluster), and claimed that in most clusters, 14% - 18% of the nodes (people) are chain initiators (they liked the Page by searching for it themselves). This percentage is much higher than what others have observed in other social norms. Also, The maximum length of a "like chain" is much longer than the word-of-mouth case, with 86.4% of the "like chains" have at least 4 nodes, and the longest chain being 82-node long.
