Daniel Sinker: It’s interesting, because I think I was the last person to realize that I was actually even writing a book. I’d been at the @MayorEmanuel Twitter feed for months, and as the storylines became more fantastical and more involved, I began to see backchannel discussion in the @ reply stream about turning the feed into a book. People wanted to be able to sit down with the entire story, not just have it appear in bits and pieces in their feed, or have to scroll back reverse-chronologically. They wanted the narrative. From there it was just a matter of figuring out what a book would be like. With so much of the story unfolding in real-time, it was clear that a simple dump of the account onto print wasn’t going to work. Arriving at the idea of extensive annotations was the key to understanding how the book would work.
