Some of the other issues involved, IMHO, are social dance versus competitive -- how do the styles differ? (You got that one, SD) Dance syllabi and manuals, what are they, how did they develop, and how are they used? What is the medals system? Why get certifications at all? What are some of the more technical aspects of the different dance styles? What are the dances within each category of ballroom dance? What about those "minor" ballroom dances? How come the International Style competitors come to the U.S. and kick butt competing in American style, though they've spent their careers training in International style? And many more ...
Come on, you ballroom folks, put in your two cents worth.
