This very interesting article also assumes that there is a alien world with technology at least as advanced as ours, who have eyes, who can observe visible light, who care about astronomy, who care about SETI? For all we know the universe is filled with advanced civilizations who use echolocation, who live exclusively underwater, whose skies are completely beclouded (like Venus)? THINK ABOUT IT!

I agree with CHUCK (post #8): You live in one of the biggest, most densely populated cities in the world! You should be thrilled that you can order any type of cuisine and have it delivered to your apartment! What's the point in living in the Big Apple if not the ridiculously wide variety of food available? I appreciate a good snark as much as the next smartass, but is sticking a bright yellow sign on your door really preferable than some litter on your mat?
