Twitter Co-Founder Evan Williams has an ambitious new plan: to shift our daily reading habits away from consuming incremental news bites and towards engaging with enlightened ideas curated by an intelligent algorithm. Ordinarily, such a goal would be laughably utopian, were it not for the fact that Williams is among a handful of Internet pioneers who have disrupted the media industry multiple times.

Open collaboration systems like Wikipedia need to maintain a pool of volunteer contributors in order to remain relevant. Wikipedia was created through a tremendous number of contributions by millions of contributors. However, recent research has shown that the number of active contributors in Wikipedia has been declining steadily for years, and suggests that a sharp decline in the retention of newcomers is the cause. This paper presents data that show that several changes the Wikipedia community made to manage quality and consistency in the face of a massive growth in participation have ironically crippled the very growth they were designed to manage. Specifically, the restrictiveness of the encyclopedia's primary quality control mechanism and the algorithmic tools used to reject contributions are implicated as key causes of decreased newcomer retention. Further, the community's formal mechanisms for norm articulation are shown to have calcified against changes – especially changes proposed by newer editors.
