Slouching To Authorgeddon Pt VII

According to a study by Lulu, a provider of print on demand books, each year shows a rise in the number of people who have published a book, accompanied by a decline in the number of people who have read one.  Extrapolating these figures suggests that in 2052, we will reach "Authorgeddon," when "the number of new number of new books published in America will first surpass the number of Americans who read even a single book each year."
So how do you attract readers if everyone's an author?
