I largely agree. I'm very much coming at this from the angle of 'knowledge work', and think a system of this kind is most useful to (though definitely not only useful to!) scientists, engineers, designers, lawyers, journalists, etc. While the population of knowledge workers is admittedly much smaller than the population on the whole, though, it's still sizable. Knowledge workers play an incredibly important role in our society, and anything that can amplify their intellectual capabilities is well worthwhile in my view.

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.
