I've always wondered why ballet doesn't court the figure-skating crowd more actively. It seems a natural crossover to me. And, at least in Canada, there are LOTS of figure-skating fans.
Helene can probably speak much more knowledgeably about this, but as someone who watches a lot of dance as only a little ice skating, I have to say that it's one of those situations where there's almost too much crossover, but not enough. There are fundamental aspects to figure skating, having to do with actually sliding along the ice while standing up, that seem to act at cross-purposes to the outward rotation at the hip joint that is the heart of ballet technique. For me, I see this reflected throughout ice skating, so that aesthetically it's close, but it's-not-quite-the-same-thing -- this can be really disorienting!
