The Anatomy of the Facebook Social Graph
"... we characterize the assortativity patterns present in the graph by studying the basic

Four Degrees of Separation
Remember what I had been saying since several years ago:
Social networking/applications could merge with online dating for fun, for flirting, for entertainment purposes, for instant gratification.
Social networking and online dating for serious daters are like water and oil, they will never mix.
Online Dating for serious daters does not need to be more social, it needs to be more effective/efficient. It needs to reduce the false positives problem.
