Many organizations and individuals in the social sector face challenges in their capacity to deliver social services due to a lack of resources and formal recognition. In this environment, there is limited opportunity to sustain social development. To support this practical need, we espouse the application of information systems to support social development initiatives. In particular, we examine the role of social media for social development through an investigation of Malaysian soup kitchens. The soup kitchens under study were able to use social media to grow and innovate their organizations, leading to an increased capacity for social development. We examine the use cases of social media in facilitating day-to-day operations, as well as analyse the relationship between social media use and capacity development in creating social outcomes. We conclude with a discussion on lessons learned and provide a set of guidelines for future social actors engaging in social media practices.
