Steve -- If you don't sense a profound change occurring in human communications, I can only ask: What tools are you using? What are you reading? ProfNet, for one, will be profoundly changed by micro media, and I applaud Elizabeth for laying out a new model for that's directly relevant to the experiment we're conducting in ExpertWiki. I'm encouraging all ProfNet members to follow Elizabeth's thread because she's creating a conceptual framework for our next steps. As a dues-paying IAOC member, I'll just add that I think we should encourage Elizabeth to continue this discussion on this blog for as long as she wishes to do so. Let's not criticize but, rather, give her the best of our thinking. That's the best kind of collaboration there is. Dan
