Too big! Seriously, this post contains too many elements to readily reply to in a coherent way.

Is that a problem? I tried to address it with the tl;dr and the conclusion.

I didn't find it too big. I just found it too bundled up, but that's probably because the topic is naturally like that. By 'bundled up' I mean, I found the article felt as if it interleaves too many concepts without first trying to make them all explicit. That said, am working on an article along lines of (introverts/intrinsic motivation vs extroverts/extrinsic motivation) so i understand the complexity involved.
