Goodreads

I am a member of a website called Goodreads which helps you keep track of the books you have read.  You can review the books you have read after you finish them and you can read the reviews of other members.  The website also recommends books to read based on the books you finish.  So when I finish listening to an audio book, I rate the book and write a review.  I wrote a good review of The Sleep Solution saying how I was trying the Ice Bucket Sleep Challenge and it was working.  A couple of days later, I got a message saying that someone had commented on my review.  I went to look at the comment and it was from the author thanking me for reading his book and giving it a good review. I guess he is a member of Goodreads too.
