Cover Designs in Decline?

Writing in the New Yorker, Tim Kreider explains why he thinks that high end book cover designs are in aesthetic decline. He suggests that the field is afflicted by a degree of conformity probably exacerbated by the Internet. "There’s clearly some brutally efficient Darwinian process at work here, because certain images—half-faces, napes, piers stretching into the water—spread like successful evolutionary adaptations and quickly become ubiquitous". He gives examples and harks back to the inventiveness and frequent weirdness of covers designed for pulp science fiction. Other culprits include the decreasing popularity of hand lettered titles (making something of a comeback, in my opinion). Children's and young adult titles are lauded as an exception to the general malaise.
