I don't think that learning styles are myths.  They are quite effective, especially when integrated with an understanding of multiple intelligences.  I like learning about ideas, the history of ideas, and why people believe what they do.  These "likes" have contributed to my being a life long learner and explain why I am successful in some areas.  I had to employ an understanding of personal learning styles to help me achieve in areas in which I did not do well.  You can blend learning styles and multiple intelligences because the strengths/weakness of one is offset by the other.  Applying an integrated approach of these two methods addresses diversity issues at many levels.
