If the target audience is knowledge workers then this is a nice step in a better direction. Bear in mind, though, that the goal of a knowledge worker is to understand content so the focus of any such project probably shouldn't be on enhancing the manifestation of graph theory on the web and rather on the methods of education available.

Focus on how the content is presented to the user rather than the connections between content, because at the end of the day it's the content I care about and not the connections.
