Sitting and listening to J.C. address the CNI opening plenary. She's hitting a few good marks for me. She's author and partnern on Joystick Nation, Inc. (NB: which has a website under construction). Her talk began with the issue of "context" being a critical element in identifying or working with knowledge and information. She put down "metadata" yay as requiring more effort than perceived value. Blogs and Wikis make up an important part of the presentation as being new components of "social software." I'll add any useful links later.
