eigentlich erklärt crisscrossed, was ein Barcamp ist, aber für viel spannender (weil mir Barcamps ja mittlerweilie geläufig sind) finde ich dieses Betrachtungsweise:
To me, it seems that unconference is overlapping with open space, which is more of a method while behind unconference there is a philosophy. It is fascinating how unconference motivates people to network and collaborate. In that regard, it is quite different to conventional conferences because it is a bottom-up approach, highly creative and can be used for all sorts of topics. In Canada transit camp discusses local development, and in France a wine camp was organized. Some other examples are Kenya or India where Barcamps were also organized. Lastly, this fascinating initiative is explained in detail in a book, which is of course written as well in a wiki.
