The perpetual spinner thing happened at my last job too, and I developed the opinion that putting a spinner into your site at all is a sign of incompetence. For any normal CRUD app, it should take milliseconds to do whatever task. Even with network delays, 150 milliseconds is a reasonable upper bound for end-to-end processing. If you have an animation at all, then your thing is either ridiculously slow or broken. Either way the animation is a crappy attempt to paper over a bad job.
