However, they rely on two fundamental assumptions (i.e., reliable Internet connectivity, literacy) that exclude scores of potential end-users, especially in the developing world. Including these potential end-users will require lifting those two assumptions. This paper is a first step towards inclusive social networks in the developing world. It proposes and validates a two-layer system architecture. The proposed architecture allows end-users to access the social network with low-end cellular phones, using voice and Short Message Service (SMS), in addition to traditional access via a computer or smart phone, using keyboards. We have built a proof of concept prototype in which poorly literate end-users are included in two simplified dedicated social networks (a small farmers’ social network and a motorcycle taxis’ social network).
