The curious incident of the books on the Kindle: Do people actually read the ebooks they buy?

If you had a pile of 300 books in your house waiting to be read, what would you do? Would you go out and buy any more books? I doubt it, even if you could battle your way to the front door. Yet if you’d got 300 books on your Kindle/iPad waiting to be read, would you stay in and click on any more ‘Buy It Now’ logos? More than possible. Because you probably wouldn’t even have noticed how many books were on there.
