One tidbit from the article:
Barnes & Noble has determined, through analyzing Nook data, that nonfiction books tend to be read in fits and starts, while novels are generally read straight through, and that nonfiction books, particularly long ones, tend to get dropped earlier. Science-fiction, romance and crime-fiction fans often read more books more quickly than readers of literary fiction do, and finish most of the books they start. Readers of literary fiction quit books more often and tend skip around between books.
Those insights are already shaping the types of books that Barnes & Noble sells on its Nook...
