Mobile Community Design...is an academic blog I just found focusing on:
Design of mobile communication devices that facilitate mobile communities, Computer Support Cooperative Work (CSCW), sociotechnical systems, usability, Human Computer Interaction (HCI), ethnography, User Centered Design for mobiles, groupware, social networks, mobile reputation systems.
Recent posts covered Using technology to create positive norms and Effects of size on physically distributed groups.
It's run by a Ph.D. student at the University of Queensland in Brisbane, Australia. He's looking for collaborators, so why not send some postings his way?
