Rob van Kranenburg presented his thoughts on the increasingly strained relationship between formal and informal networks. He showed a rich collection of examples of bottom-up online and sensor-based innovations (wikipedia, commons-based peer production, thinglink) that create their own informal networks, running parallel to top-down systems auch as nation states and the EU. This talk was part of the Organisation, Strategy & Design Seminar Series held at the London School of Economics. After the talk Rob invited us to brainstorm in small break out groups about sustainable bottom-up innovations. My group came up with an idea for local recycle stations that extract raw materials from our disposable goods and produce new stuff on demand in replicators.
