Evan Applegate has probably the best podcast on cartography going. I was fortunate enough to site down with Evan and talk about my work.
New York City cartographer and chief design officer on using library archives, train-mounted GoPro footage and his own two feet to plot every track in the New York City subway system, a brush with cubicle-based urban planning at the Port Authority, testy-yet-productive correspondence with railfans, the unshakable authority conveyed by the Google Maps style, how your cartographic project should answer a question, and learning that the obstacle to building a subway extension is not money (“What’s four billion dollars?”) but belief that it can be done.
