I think your blog and the comments are on the wrong track and this is why the take-up of EQ is slow.  While Goleman defined EQ and why it is important, he did not describe how to lift EQ in his seminal book.  The main reason is that he did not have a theory of core emotions.  He has since gone down the competency route which is another wrong track.

I think the major problem stems from a confusion between transient emotions (driven by the amygdala)  and temperament (which is our genetic predisposition to how we emotionally react.)  To really understand emotional intelligence you need a theory of temperament and I have blogged on what I think is the most practical for managers and salespeople.  http://www.emotionalintelligencecourse.com/eq-blog/temperament-is-more-important-than-transient-emotions.html
