Show HN: Arandomquote.com Great books summarized in 5 quotes

I love books and I created http://arandomquote.com because I wanted to share great quotes from books that I read. In the future I would like to add amazon affiliate links but first I want to know how to improve the page and what people likes.

Another idea that I have is a newsletter so you can receive 5 quotes from great books each week in your inbox. Also you can play the guess the author game here http://arandomquote.com/guess/

I'm looking for ideas, what do you like, what would you change, etc.

thanks
