A five or so line summary of the concepts of any given philosopher will be necessarily incomplete. It's certainly not going to handle things like the evolution of their own ideas over time (and many philosophers contradict their own early work with later works). On the other hand, as a rough guide to the structure of the history of philosophy, this is a very interesting approach. All philosophers are standing on the shoulders of giants. They are influenced by and comment on each other's ideas. Putting those concepts into an easy to follow link-based format is a terrific idea, and could be very useful to a lot of us who study philosophy.
