"Love the Kindle Spy software to help me see trends in the industry"

Love the Kindle Spy software to help me see trends in the industry, as well as verify how I am doing, in a snapshot graph, compared to other authors in my genre. I also use it when I'm contacted by authors I don't know, or when I want to learn about what successes others are having that I can learn from.
