This paper investigates a hidden dimension of research with real world stakes: research subjects who care -- sometimes deeply -- about the topic of the research in which they participate. They manifest this care, we show, by managing how they are represented in the research process, by exercising politics in shaping knowledge production, and sometimes in experiencing trauma in the process. We draw first-hand reflections on participation in diversity research on Wikipedia, transforming participants from objects of study to active negotiators of research process. We depict how care, vulnerability, harm, and emotions shape ethnographic and qualitative data. We argue that, especially in reflexive cultures, research subjects are active agents with agendas, accountabilities, and political projects of their own. We propose ethics of care and collaboration to open up new possibilities for knowledge production and socio-technical intervention in HCI.

Free and/or open-source software (or F/OSS) projects now play a major and dominant role in society, constituting critical digital infrastructure relied upon by companies, academics, non-profits, activists, and more. As F/OSS has become larger and more established, we investigate the labor of maintaining and sustaining those projects at various scales. We report findings from an interview-based study with contributors and maintainers working in a wide range of F/OSS projects. Maintainers of F/OSS projects do not just maintain software code in a more traditional software engineering understanding of the term: fixing bugs, patching security vulnerabilities, and updating dependencies. F/OSS maintainers also perform complex and often-invisible interpersonal and organizational work to keep their projects operating as active communities of users and contributors. We particularly focus on how this labor of maintaining and sustaining changes as projects and their software grow and scale across many dimensions. In understanding F/OSS to be as much about maintaining a communal project as it is maintaining software code, we discuss broadly applicable considerations for peer production communities and other socio-technical systems more broadly.
