eLearn Magazine has published my response to a column by Michael Feldstein in the same publication a month ago. In his column, Feldstein warned of the danger of 'cascade phenomena' in networks - things like following a fad or buying into a market bubble. He recommends that networks be managed in order to reduce the risk. In my response, I argue that managing the network would exaggerate the problem, that cascade phenomena occur because networks are not sufficiently distributed (resulting in a 'power law' configuration), and that the best way to minimize cascade phenomena is to maximize connectivity.
