Which variables get set when you do X is fairly factually verifiable. How do you factually verify a data structure is cool? More helpful? What is the task at hand? If I am playing Skyrim and trying to decide weather or not to initiate followers into the Blades of Skyrim, then the link you posted is most helpful. On the other hand I am not sure what task I would be undertaking where a bunch of data structures whose only commonality is obscurity would be truly helpful.
