Maria Popova, Editor of Brainpickings, discusses how, with the world's knowledge more readily available to us than ever before, the fragmentation of our interests is driving us to seek out more and more of what we're already interested in. How, she asks, can we master the architecture of human knowledge in a way that takes advantage of the "Information Age", yet broadens rather than contracts our intellectual and creative horizons, both as individual consumers and as publishers of information?
