(Challenges and Opportunities of) Documentation Practices of Self-Organized Urban Initiatives.

In this chapter, we discuss the documentation practices of two citizen initiatives in Helsinki and the role of current social media infrastructures and artefact ecologies in supporting them. We point out how social media and other digital technologies are important catalysers in the initial steps of both endeavours, providing seeds for documentation practices to emerge. However, as practices stabilize and more information is accumulated, challenges related to access, effective archiving, reach and reuse start to appear. The chapter introduces some implications for social media design and the structuring of participatory design processes linking these areas to the construction of knowledge commons.
