Primarily attempting to create viral applications is a method that has certainly been employed by numerous Facebook application developers. Stanford University even offered a class in the Fall of 2007, entitled, Computer Science (CS) 377W: "Create Engaging Web Applications Using Metrics and Learning on Facebook". Numerous applications created by
