This article seems somewhat balanced, but a few sentances such as "He discovered that he could achieve the same results as" and "Many new questionable NLP schools and companies opened up and greatly altered the field." and "Certainly, he is acknowledged as being remarkably effective at working with a wide range of problems," just don't seem neutral to me. They're making claims about NLP in general, and Bandler's version of NLP in particular that are unsubstantiated. 

 The final sentance "Proponents point out that theory is not where Bandler's interests lie  he is interested in what works." is almost identical to the one Heron removed. Perhaps we could get a few more direct quotes in there so that it's not the article making the claims, it's Bandler himself.
