I just gave a talk at the 31st annual Chaos Communication Congress in Hamburg. The blurb:

“The internet may be the nervous system of the 21st century, but its main business purpose is helping marketers work out how to make people buy stuff. This talk maps out a possible alternative, where consumers co-ordinate online, pooling their data and resources to match demand with supply.”

It was live-streamed and the video should be up on the ccc-tv soon. Slides from the talk are available here in PDF or ODP

Thanks to all the organisers for running such a great event!
