Commons and Infrastructure.* This is, IMHO, one of THE issues we have to deal with if we want to expand the commons. The following is a personal summary of the debates at theEconomics and the Commons Conference (ECC, Berlin, May 2013). It will be published in two parts. The first one is based on the Keynote of the Infrastructure Stream at ECC (presented by Miguel Said Vieira; prepared by him & Stefan Meretz). While re-listening the keynote, summarizing their ideas and paging through my notes from the European Deep Dive, I added some of my own ideas and a few examples that came into my mind. The second one will be based on the discussions during the stream sessions.
