[metaphor]

I can see your attempts to generalize, i.e.

  Acquisition := Most useful when we're studying
  Application := Most useful when we're working
  Cognition := Theoretical knowledge
  Action := Practical steps

...but in my mind, the older quadrant labels were immediately insightful at a glance.

Glad to learn that you've given your system a discoverable name though; for years since that PyCon presentation, I've informally recalled it as "the idea by that Django documentation guy".
