Social networks affect all of our lives; the people we know influence what we're exposed to and the actions we take. Gaining weight? Blame your network. Got a job promotion? Thank your network. In the developed world, the term "social networks" often illicits thoughts of Facebook, LinkedIn, Twitter, Instagram and many, many more. In the rural developing world, networks still depend, for the most part, on offline interactions. Access to information is by word of mouth, and a few central individuals often disseminate information from the top down to the remainder of a village.
