The interesting thing for me is that this provides a strong justification for using social networks in learning: wikis can be places where people can store the information about problems they’ve solved, discussion boards and profiles fill the need of finding expertise, blogs may support people in their problem-solving as well, serving as a way to share questions and get feedback. The social network provides the rest of the support around the courses which really only serve the situation where a major skill-shift change is needed.
