Abstract
Collaborative user-led content creation by online communities, or produsage (Bruns 2008a), has generated a variety of useful and important resources and other valuable outcomes, from open source software through the Wikipedia to a variety of smaller scale, specialist projects. These are often seen as standing in an inherent opposition to commercial interests, and attempts to develop collaborations between community content creators and commercial partners have had mixed success rates to date. However, such tension between community and commerce is not inevitable, and there is substantial potential for more fruitful exchanges and collaboration. This article contributes to the development of this understanding by outlining the key underlying principles of such participatory community processes and exploring the potential tensions which could arise between these communities and their potential external partners. It also sketches out potential approaches to resolving them.
