I wonder if, setting quality aside, the kinds of tricks (is "tricks" right?) that skaters do becomes more similar with technology. That is, skater X was going to do some random trick, until X learned that skaters Y and Z were doing quad jumps, so X figures he must do quad jumps now. In other words, if we could represent skating routines as vectors, would the average cosine distance between all those vectors be increasing or decreasing?
