Robin Sloan used to work for Twitter, but is better known for writing Mr. Penumbra’s 24-Hour Bookstore, which is a novel about, among many other things, Google. Here, he talks to an interviewer about how digital tools can be married to a different sensibility from the usual instant/huge/shallow/short-term approach that we tend to associate with them, and how the slower, more thorough process of, for example, traditional publishing has something to be said for it.
