For the same reason that we use an email list, Walt, instead of visiting
each of our fellow SETIzens in the flesh. One communications attempt (be
it radio or supernova) can reach (potentially) thousands of civilizations.
That's a lot cheaper than thousands of trips, even if they have to drive
over to the one star they're exploding.
