Two days of presentations, demos and discussions about Social Semantic Web approaches, tools and benefits are over. We had more participants than expected – social semantic collaboration seems to be indeed a hot topic. Kingsley Idehen’s keynote about the Data Web did not just excite CSSW participants but visitors of other SABRE conferences as well. We were very happy to incorporate some late breaking additions to the program, among them Santtu Toivonen’s talk about “Web on the Move – Landscapes of Mobile Social Media” and Marc Fleischmann’s inspiring sMeet presentation “sMeet – Bringing a Rich and Realistic Communication Experience to the Global Virtual Society”. CSSW concluded on Thursday with a panel discussion about obstacles and benefits of the Social Semantic Web and a come together in the restaurant Pier1 at lake Cosupden.
