In the latest discussions of children and young people’s new geographies of leisure and pleasure, one controversial issue has been how digital technologies co-produce and reconfigure young people’s everyday worlds. This article draws on semi-structured interviews with 40 young people who regularly use social networking technologies in their nightlife experiences in Zurich and Lausanne, two nightlife hubs in Switzerland. Informed by Danah Boyd’s concepts of ‘collapsing contexts’ and ‘imagined audiences’, this article enables a critical engagement with young people’s emerging understanding of their nightlife contexts, which are increasingly permeated by networking technologies. I show how social networking spaces facilitate the coming together, or collapse, of various social contexts which induce young people to imagine multiple audiences, including authority figures, in their nightlife practices. These collapsing contexts and imagined audiences, I argue, present new perspectives on debates about control and surveillance in young people’s contemporary urban nightlife.
