Wikipedia has matured as an open source collaborative project, featuring a robust governance structure that has emerged over the project’s 13 year history. While the policies and guidelines help shape the creation of quality content on Wikipedia, one area of the community structure that is receiving a great deal of attention and thought is the experience of newcomers. Research shows that ,of late, newcomers find themselves in a hostile environment that does not welcome their contributions. With Wikipedia surviving on the goodwill of volunteers, chasing away newcomers has implications for the long term sustainability of the movement. As such, researchers and community members alike are rethinking how to support newcomers so that they will be more inclined to stay with Wikipedia. As someone who thinks a lot about the experience of newcomers in online collaborative communities, I was excited to receive news this week that I along with two other Wikipedians received a grant from the Wikimedia Foundation to develop a new mentorship system that matches newcomers with experienced Wikipedians based on the skills newcomers wish to learn. The aim of the project is to support newcomer socialization and learning with the broader goal of supporting newcomer retention. Over the next six months I will work on this grant as a researcher, examining the newcomer experience in the system we design as well as the outcomes of their participation. This project should shed light on some of the broader issues of expertise sharing and newcomer socialization and will ideally make valuable contributions to the research and design around development and management of online collaborative environments. I look forward to writing here about what I find over the next six months.
