FLOSS developers as a social formation

Developers of Free/Libre and Open Source Software (FLOSS) are often referred to as a community or as a scene. But so far this seems mostly just a rough expression. This paper takes a closer look at FLOSS developers and their projects to find out how they work, what holds them together and how they interact. Community and social movement seem not to apply as descriptors. Looking at norms, values, structures, and conflict resolution, a hacker subculture appears which is compartmentalised into differently organised projects. By testing empirical findings against various theoretical approaches, ideas for further research are identified.
