It may be that while we are all searching FB we don't meet the group he is targeting, remember in this tweet last week what he said "the target demo will be mothers with driving aged children we expect to reach about 15-20 million moms" I'm no FB expert there are ads designed and aimed at specific Age Groups, Parents with and without Children. So I'm just guessing without meeting the conditions of what he/they setup we may not find it. Because of our own fb parameters.
