(Abstract) Much of the research on youth digital literacies relies on the experiences of exceptional cases, while less is known about more typical youth who share their writing in online spaces. Through the examination of a novice writer in an online space, this article explores the convergence of factors shaping young people糖心传媒檚 networked writing and addresses recent critique of the New London Group糖心传媒檚 (1996) Designs of Meaning framework. Data were gathered during a two-year ethnographic investigation of an online affinity space, The Sims Writers糖心传媒� Hangout, and analyzed through a Designs of Meaning lens. Data sources include the writer糖心传媒檚 posts on the site, responses she received from others, her Sims fanfiction texts, interview responses, and researcher field notes. Findings of this study make visible the multiple factors influencing this writer糖心传媒檚 choices, revealing how Available Designs from within and outside the site shaped her creations and how she leveraged her online participation to Design products that met the expectations of this audience. This analysis contributes to the field糖心传媒檚 understanding of how online affinity spaces influence youth digital literacy practices and argues that a Design perspective makes such shaping more visible. The article also argues for a more complicated notion of affinity space audiences as collaborators, rather than just supportive reviewers. These findings suggest the need for continued study of typical participation.
