I've always thought of gravity as a field of some kind even before learning about fields as a mathematical construct. Never worried about the speed of propagation of a change in field, still don't, but it looks like somebody ought to, so it is good to know that such changes propagate at the speed of light. Waiting for news of the gravitational blue shift.
