This paper reports our experience with developing a Business-2-Social (B2S) platform that provides necessary support to all this platform's constituents, namely business processes, social media (e.g., social network), and Internet of Things (IoT). This platform is exemplified with smart cities whose successful management requires a complete integration of IoT and social media capabilities into the business processes implementing user services. To ensure a successful integration, social actions, that a smart city would allow citizens execute, are analyzed in terms of impact of these smart city's business processes. Reactions to these actions are tracked and then analyzed to improve user services.
