Except that Google would lose its aesthetic appeal and lose 50% of their audience who use it in the dark hours.
I would promote own dating service.. And I really hope that goolge will not do that with google romance in the nearest future
I would drop the "do no evil" policy and start terrorizing the net. I would do more banning of IP ranges and even countries that are spamming or just unprofitable. The homepage would be turned black with no search field on the birthdays of Richard Nixon, Ronald Reagan, and George W. Bush to honor the patron saints of evil.
If you were to own Google.... Then "world hunger" would cease to exist.. I would make it a point to help those less fortunate then myself especially the children whom have nothing to look forward too in thier youth. thx malcolm
