Writers are bombarded with reasons to change their writing. Reader preferences, editor requirements, commercial considerations, fashion and quite a few more get onto the list. So do we really need another pressure?
Well maybe it won’t turn out that way, but when I heard that e-readers track and report statistics on your reading habits, a tiny bit of me died. Now the world of traditional publishers will know not only what books people buy, but whether those books get finished and how long readers spend on reading them.
I predict this will lead to the pressure to make certain points in novels more exciting to hold reader interest, or re-working a chapter for a second edition of a book to eliminate the point readers are giving up.
Worse, it could lead to an only-pay-for-what-you-read model. Ye gads.
