Some years ago we wrote quite a bit about the history of Facebook and the Winklevoss Twins. The "Winkelvii" continue to be in the news in a big way (Quartz: "Mark Zuckerberg is five years behind his nemeses, the Winklevoss twins, on cryptocurrency") through the virtual currency Bitcoin and the virtual currency exchange Gemini, as reported in the New York Times by Nathaniel Popper: see How the Winklevoss Twins Found Vindication in a Bitcoin Fortune.
These are great stories about human innovation and our world in a state of flux!
