Going Meta
Paul Matthews · 2016
This paper presents research into the way norms are developed, expressed and enforced on sites that are part of the Stack Exchange (SE) social question-answering network. This network has a number of topical knowledge exchange communities using similar underlying software, enabling a focus on variation in social design. SE also separates community-related discussion from topic-specific content through the use of its "Meta" sub-sites. These were analysed together with their main sites for variation in the development and enforcement of norms. Norms expressed through explicit community policies seem rather less important than those embodied in busy discussion threads on the Meta sites. While Meta participation was fairly uniform across communities, different emphasis on scope and quality led to variation in Meta discussion and the way that norms were enacted through question closures. The social distribution of moderation work was also uneven between sites, with some sites having a few highly active moderators involved in question closure. The level of closures across the sites studied did not seem to significantly discourage participation. Indeed, modelling the effect of closures on quality and engagement indicated that low levels of closure enable "legitimate peripheral participation", the process by which newcomers can become inducted and make contributions of increasing quality over time.
