someone here was asking why then do ballet dancers take spotting so seriously, if others are saying it's really not that important or helpful with regards to avoiding dizziness... I don't know all the ballet terminology, but I think spotting in ballet and in say salsa are completely different things. Most ballet dancers aren't doing repeated, rapid spins as one might do in salsa. In ballet, their pirouettes or whatever are usually combined with a leap in the air, during which they do one rotation, they land, leap again, do another rotation, and so on. So it is much "easier" for a ballet dancer to spot, because they are only doing one spin at a time, and at a much slower pace than a salsa dancer (much less an ice skater!) would. I think when they talk about spotting in salsa, it's not so much a "physical" spotting (I've always wondered how it can be possible to actually spot during consecutive rapid spins) as much as "mental" spotting, or just keeping in mind/visualizing where your start/end point should be for your spins.
