Google wants you to play a guessing game.
 

Rather than directly proclaiming that it had surpassed its archrival Yahoo in the battle for index supremacy, Google said it would ask visitors themselves to estimate how large their index has grown to. Google's chief executive, Eric Schmidt, said the company would remove the current number from its home page (most recently "Searching 8,168,684,336 Web pages,") and instead ask users to guess the size of the new index. Mr. Schmidt did not rule out the possibility that a prize would be awarded to the winner.

i dont care enough to guess

if the prize was good enough I'd guess. But isn't it changing constantly? No one would be able to guess it.
