Hope King heads over to the Instagram office in NYC to chat with the company's Android engineer Lola Priego. Priego discusses how she is bringing the app overseas and breaking into emerging markets. One of the biggest challenges is overcoming limited network connectivity. She says the devices and networks used in emerging markets are very different than the U.S. Priego shares stories from her team's recent trip to Indonesia to observe problems with connectivity. She says building empathy with users is not the same as trying to think about their problems. Instagram's goal is to make the app work smoothly and load everything as fast as possible. To make the user experience better, Instagram looks at "sad metrics." The company aims to reduce the number of users that are sad because the photos are not rendering.
