We first observe that the popularity of contents is correlated with the visibility of their authors, and can thus be explained by social influence. We then provide evidence of a feedback loop between the visibility of contributors and the popularity of their contributions, which increases the importance of social influence over time. Finally we quantify the effect of social influence in making each story popular and show that this effect tends to favor less interesting stories.
