Knowledge and expertise in a hybrid world

Predicting the future has always been a dangerous game, but I am willing to put my marker down for a hybrid world, with a mixed economy of physical and digital reading. Some recent statistics from the US are interesting - a year ago 70% of ebook consumers said they read exclusively in the digital format, while one year later that number has dropped by 10% to 60%. And ebook growth is slowing dramatically - in September 2011, growth was still 101% year on year, but by April 2012 it was only 37%. Even 50 Shades - originally a self-published ebook as we all know - has split equally between print and ebooks in the US.
