As a way of extending perspectives of writing and learning, this thesis explores everyday literacy activities and their role in function in shaping people's activities. Taking up an autoethnographic approach to studying the mundane literacies of everyday life, this thesis offers a fine-grained analysis of the processes and practices involved in two specific literate activities I have engaged in over the two years: creating a mixtape for a friend and streaming my participation in online video games. As key findings, the analysis of these everyday literate activities suggests that the interactions between people and social contexts figure prominently in the production and use of everyday texts, that everyday life is profoundly mediated by digital literacies, and that everyday literacies are often central to people's academic and professional lives. Ultimately, these analyses point toward the need for further inquiry into digital literacies, and to the potential pedagogical benefits of encouraging students to examine the mundane literacies at play in their everyday lives.
