During such a meeting I, Bence Damkos, and other chapter luminaries got to discussing many apparent cultural paradoxes taking place in the virtual community. Since I was studying the theory of games at the time I began to notice that some of the situations were very similar to a classic game such as the prisoner's dilemma and the battle of the sexes while others resembled second-price sealed actions and bargaining games.
