First of all thanks a lot to the whole barcamp-team for organising this well done event. I enjoyed my first barcamp experience, although it was very difficult to listen and understand each other due to the bad sound in the rooms (it was one big room divided in smaller rooms/boxes), especially sharing thoughts/experiences and hosting a session together with Peter Bihr - topic: "user-generated content and collaboration" - Peter summarized it very well here. I just would like to add, that we also talked about the problems we have concerning collaboration in means of "collective action". Trying to overcome the old limits of institutions of participation we notice the need for new rules. In my article for politik-digital I have a nice quote of Clay Shirky (@picnic08 conference Amsterdam):
"We need for collective action a new form of incorporation which works in front of the state in the same way the GPL License works for software."Of course we did not solve this problem, but hopefully raised the awareness. Seems to be classical barcamp style that raising questions is more common than offering answers.
