The Information: How the Internet gets inside us by Adam Gopnik at the New Yorker is one of the best and most sensible things I've read about that crazy force/source called the Internet. He reviews all the major writers on the subject and boils them all down into an amazingly clear essay. You may have read one or two of these and made a handful of observations about our relationship with the digital world, but Adam Gopnik, one of our best essayists, writers and thinkers, sums it all up so well that you're doing yourself a disservice if you don't read his thoughts on the subject before engaging in any further ruminations of your own.
Below are all the authors and books he mentions in the article. It's practically a syllabus for an amazing and contentious media studies class, no? Best of all, the article is bookended by an image of Hermione Granger in the stacks of the library at Hogwarts. Enjoy and let me know your thoughts.
