But you'd be broadcasting to the entire universe. Also, seems like you'd get a lot of collisions. Everybody in the universe broadcasting via gravity waves would be doing it on the same "frequency" (so to speak) right? You'd also be perturbing the entire universe. Unlike radio waves, the gravity waves are going to have a very real effect on the objects through which they pass. If you're using gravity waves to communicate with somebody zillions of light years away, seems like you'd disrupt all the nearby star systems.
