Actually I think it's quite meaningful, due to its recognition of introversion and extroversion as more of agencies which aren't mutually exclusive.
Anecdotally, I identify with this much more closely than other analyses. So much so that this is a perspective altering epiphany-class insight. Really good stuff.
I expected the majority of readers would respond by defending the model they were used to and attack alternatives, never considering that their model would wither equally or more from such an attack. The standard model most people have has no basis, it's just commonly held.
