A company called Kno has been distributing iPad versions of college textbooks since June. The company says it has 100,000 textbooks digitized and available and for sale at a cost of 30-50% less than the physical book. Plus: lighter. Now, Kno is making those same books available on the web and through Facebook. Kno is adding the ability to discuss what you’re reading with friends and take quizzes on what you’ve just been reading by taking the text and blocking out key elements.

So it’s good for studying! Not cheating, STUDYING! Sure, college kids, just keep telling yourselves that. Why in my day (grumble grumble) Cliff’s Notes (grumble grumble) by cracky hey you kids get off my lawn.
