It makes no sense to point these radio-telescopes towards space when there are many locations on Earth to search for intelligent life:
1600 Penn Ave, Congress, EPA, NPR....
Actually, there's a better chance of detecting intelligent life in the vacuum of intergalactic space than in those places. Let's hope that intelligent life will be found at 1600 Penn Ave, on January 20, 2013. Maybe the telescopes can be aimed first toward some polling places on Nov. 6, 2012, to see if there are any signs of intelligent life there.
