This Cornell Info 204 – Networks class blog is exemplary. It seems that the students scour around for information related to the class and post entries – that are then reviewed by (and commented by) the class and the rest of the world. This is a much better model for an ideas-history-and-paradigms class than handing in homework and essays. I’ve browsed around it, and the postings describe the myriad applications of network-oriented thinking we can see around.
