“The apps start out with seemingly simple motivations, as entertainment that could lead to a business: Facebook is for connecting with friends and family, YouTube is for watching videos, Twitter is for sharing what’s happening now, and Instagram is for sharing visual moments. And then, as they enmesh themselves in everyday life, the rewards systems of their products, fueled by the companies’ own attempts to measure their success, have a deeper impact on how people behave than any branding or marketing could ever achieve.”
