This document discusses how social networking is moving from the web to mobile phones, especially in developing countries. It notes that while most people in developed countries are connected via Facebook and Twitter on the internet, in developing countries over 6 billion people have mobile phones but only 2 billion have internet access. As such, social networking experiences need to be developed for basic mobile phones, not just smartphones, to connect the billions of people who can currently only access social networks through text messaging on their mobile devices. The document provides examples of how SMS-based social networks could work and case studies from one such network in Pakistan called SMSall.
