I didn't understand the idea behind this quiz until ten seconds before the end. I think it should be clarified what this quiz is about in the description. Otherwise, looking back, a cool quiz. If only I knew what it was about...
This is a very neat idea and well-executed. My only suggestion would be to find two bookends that have some relation. James Brown to Mark Twain is so random. Maybe Dan Brown to Mark Twain? This way you've got two writers.
