Which means that Amazon really does need to move to a more Apple-like human curation process for all new authors, and/or for all new titles. Doing so will immediately tank precious vanity metrics like # of titles added to the store each month. But the alternative is an ever-growing jungle of weeds crowding out the legitimate works. The more that happens, the harder it will be to eventually weed the garden.
