I think everything is worth looking at. But I bet if there is interstellar communication, we aren't privy to the medium yet. If we found a way to communicate that was much better than what we currently have, I am sure that we would send signals with this new medium. And, as any improvement will probably be of higher fidelity, lower energy, and possibly faster, we wouldn't bother with flashing laser lights.
