This lecture is from October 2014, held at the Public Library Conference in Stuttgart. But it has only recently been put online, together with all other lectures.. I think the entire conference is still very relevant.
In this lecture, I try to untangle the differences between resources that are managed as "public" and are thus connected to notions of the state and citizens and those that are managed as "free" and are thus based on notions of the commons and community. The differences are subtle, but in their consequences far reaching.
