I don't read books on KU that are often free or usually 99 cents. Most of what I read is 3.99, 4.99 and in that area. If books have been going free and cheap for long time and it was something I wanted to read, I would already own it anyway.
I keep adding books to my KU list from a wait for loan wishlist on a weekly basis. So for me, I see more books, romance, going into KU than going out. I read other genres also though. ALthough mostly romance or stuff with a romantic plot at least.
Some great back list titles also and of course the publishers I listed.
