I came across this awhile ago and think it's quite brilliant in its simplicity. The most effective theories are those that seem self-evident and are easy to digest.

This guy (Bio) is one of those professional "consultants"/writers/speakers, which means a whole lot of people think he's important enough to pay him to think.

TL;DR He goes into the different implied languages spoken amongst hierarchies and systems in which power is fluid. He comes up with classifications for the players (Sociopaths, Losers, Clueless), their "currency" (information), and how they exchange or don't exchange that information (4 talking forms).

I want to know some further examples of different "talks" people can come up with. What situations are most common at work or in game?
