Kindle Unlimited?

Amazon's latest venture.  Thoughts?  $9.99 for unlimited books/audiobooks a month on any device, as long as they are part of the program that month.  I am dying a little from the excitement of it since there are quite a few books that I have been wanting to read, but never get around to buying them. 

 

I have also read a couple of authors posts on FB wondering how they get paid for their when books are read via that program.  I didn't read the responses in the comments though, since I rushed directly to amazon to check out what they were talking about.  I'm am curious about that now...
