If it is a ‘Hugo Award Winner’ I automatically pass it by. Now, I buy self-published works from Amazon Kindle because I know they bypassed the PC Editors (with the exception of Baen).
I have published all of my work on Amazon - paperback is dead owing to this PC crap.
I really don’t see the advantage of paper-based sales anymore - too much to the publisher and very little support for the cut they take.
Amazon is no longer “The future” it is Now. More E-books are sold than paper these days....
