industry. More and more conferences and workshops discuss the impact of the users' motivation
to participate in the value creation process the enabling role of leading-edge information and
communication technologies and the need for better algorithms to deal with the growing amount
of shared data. There are many interesting and challenging topics that need to be researched
and discussed with respect to knowledge creation creativity and innovation processes carried
forward in the emerging communities of practice. COLLIN is on the path to become the flagship
conference in the areas of collective intelligence and ICT-enabled social networking. We were
delighted to again receive contributions from different parts of the world including Australia
Europe Asia and the United States. Encouraged by the positive response we plan COLLIN 2012
to be held next year end of August at FernUniverstität in Hagen. In order to guarantee the
quality of the event each paper went through a doubleblind review process. The reviews
concentrated on originality quality and relevance of the paper topic to the symposium. In
addition we invited a few renowned experts in the field to contribute to the success of the
