Personally i didn't hear much about "Thought Leadership" but my understanding is that it's a business term use to qualify an entity that is recognized for its creative thinking abilities.
It's interesting though, to realize that the qualities described in the article are/should be the same ones for a human leader that wants to shine. Ok!, we need to modify them slightly in the sense that instead of developing something external we are developing something internal,within ourselves and/or others. But, contrary to organization, we humans have the extra emotional dimension, for which we need to develop cleaver work around to achieve the same goal.
