Good information and lots to think about in this article. In order to be part of Kindle Select and be involved in Kindle Unlimited, you have to cut your e-books off from other avenues like Smashwords and other e-book distributors. Each author must decide for themselves what route to take.
HOWEVER… this only effects e-books. Print versions of our books would still be available through Barnes and Noble and other booksellers.
Still e-books seem to be what’s popular with their cheaper price tag. So much to think about…
