I am a student at Interaction Design, and I was planning to develop ideas for argument representation / debating tool as a master's thesis. One thing led to another, and my research of existing projects made me discover a wealth of international research, software development and online collaborative platforms. I realised that of course my ideas weren't really original in essence, and finally I found the Ning platform in Global Sensemaking.
This seemed to coagulate these concerns and interests into a coherent effort, so I joined in and spent some time reading some individual contributions here and there. I had a keen interest in the way the wiki was originally structured:
Thanks for any replies or ideas about current work to do in the area of representational/discussion tools in particular !
