Boris Kachka from New York Magazine on How E-books Have Become a New Literary Form:

The great hidden virtue of e-books—hidden beneath the chatter about their effect on the bottom line—is that they allow stories to be exactly as long as we want them to be. It turns out that many of them work best between 10,000 and 35,000 words long—the makings of a whole new nonfiction genre occupying the virgin territory between articles and hardcovers.
