An agent based model is developed in which a social hierarchy of leaders and followers emerges from a uniform or random social network. The formation of the social structure is driven by the desire to be an early adopter of a subsequently popular trend. The environment is related to a majority game, but introduces the importance of the timing of adoption. The proposed environment is relevant to a number of settings in which leadership and timing of decisions are important or being perceived as a trend setter is rewarded. The leadership position can be selfreinforcing. For a professional critic, for example, a cult-of-personality can dictate popular tastes, such as in art, food, and wine markets. A social hierarchy can also apply to the introduction of new products or ideas including academic research and financial market analysts.
