This presentation has been revisited especially for the ICT socieiteit of Zoetermeer, based on the original presentation by René Jansen and Wim Bouman at the Social Media Congress. Both are members of the Maatschap and Research Fellows at the University of Amsterdam. In this version Bolke de Bruin, Mark Nijssen and Tim Hoogenboom (also part of the Maatschap and the University of Amsterdam) illustrate the importance of the concept of object-centered sociality to explain the the apparent natural behavior on social media, to guide designers, by offering alternative and more realistic post humanistic-perspectives. In the first part the importance of sociality is explained, replacing the focus on functionality as design objective in social media. Sociality also forms the basis to explain why we actually engage in constructing and reproducing our social relations (on blogs, wiki's and other forms of social media). The last part explain the layered structure of constructing and renegotiating meaning (popularly devised as 'knowledge sharing') in social media. In which the construction and reproduction of social relations is pre-conditional for knowledge construction to take place, in comment sections of blogs. We hope this presentation inspires others...
