This year the OKCon is taking place in Berlin, Germany, on the 31st June and 1st July. The conference is not limited to open knowledge, but interesting talks come from the diverse fields of the commons in general. Personally, I will give an introductory talk on »Understanding Commons and Peer Production«. Christian is talking about »The Emergence of Benefit-driven Production«. The conference entrance fee is 30 Euro per day.
