… is that they try to mimic print books. It’s skeuomorphism and the horseless carriage all over again — as this excellent rant by Kane Hsieh puts it:

The problem with ebooks as they exist now is the lack of user experience innovation. Like the first television shows that only played grainy recordings of theater shows, the ebook is a new medium that has yet to see any true innovation, and resorts to imitating an old medium. This is obvious in skeuomorphic visual cues of ebook apps. Designers have tried incredibly hard to mimic the page-turns and sound effects of a real book, but these ersatz interactions satisfy a bibliophile as much as a picture of water satisfies a man in the desert.

There is no reason I need to turn fake pages. If I’m using a computer to read, I should be able to leverage the connectivity and processing power of that computer to augment my reading experience: ebooks should allow me to read on an infinite sheet, or I should be able to double blink to scroll. I should be able to practice language immersion by replacing words and phrases in my favorite books with other languages, or highlight sections to send to Quora or Mechanical Turk for analysis. There are endless possibilities for ebooks to make reading more accessible and immersvie than ever, but as long as ebooks try to be paper books, they will remain stuck in an uncanny valley of disappointment.

Right on, man!
