2017 Reading Challenge discussion

In this book, John Green uses Chicago style footnotes to incorporate the way Colin Singleton's mind works. They're facts that aren't really necessary to the plot, but they're interesting. And I like how they, plus the narrative, give the story a Train of Thought feeling. I've never seen someone use Chicago style footnotes in anything other than a college paper or published academic articles, and it was interesting to see them used this way.

Anyone else like how John Green used the footnotes? Or not?
