And yet, I continue to see anecdotal evidence that something like learning styles do exist. Granted, they don't always fit the classic visual/kinesthetic/auditory classification. For instance, I often learn a new topic best by reading about it, while some friends do better watching videos. And I think we all know that different explanations on hard topics work for different people.

Other people here have talked about stupid things people have done because of a simplistic understanding of learning styles. Ok, fine. Obviously you need to learn a topic in its own medium, and there's limits to what you can teach with song and dance. But let's do enough experiments to actually figure out what's going on, and not throw the baby out with the bathwater. There's clearly something there, IMO, even if it's relatively insignificant.
