That's rare because animation is generally not used very well.
Most webmasters go through several phases with animation.
Their site contains no animations at all because they don't know about it. They learn about animation and cautiously add a few here and there. Suddenly, they become addicted to animation, and their site gets hundreds of them per page . Someone tells them this is bad and they remove all of them. Some years later they learn the truth - animation when used properly is great, when used improperly is terrible.
