Alvin Chang, a reporter at the Wall Street Journal, is like a magician -- he makes the invisible, visible by telling data-driven stories in visually compelling ways. It’s an especially relevant skill because, in this digital world, it can be hard to wrap our heads around everything happening and our role inside of it when the forces that shape it aren’t necessarily visible. Alvin walks us through the evolution of social media and the risks that come with its use so we can be more deliberate about how and why we are using social media at UNDP.
