I have been working on writing a Facebook application since September, and I'm excited to say that today, it has been approved by Facebook and is now listed in their Application Directory.
My application is called We Read and is for Facebook users to share books with their friends. It lets you comment on and discuss books and display them in your profile for your friends to see. I used Amazon Web Services and since I joined Amazon associates, I can earn a commission whenever a user clicks on one of my books and buys it on Amazon.
Please try installing We Read and let me know what you think. I plan to enhance it with new features every week or so.
