Social media is being adopted and applied in almost every area of human activity, be it for personal applications, in education, for commercial applications or in the public sector. The rapid uptake of social media is related to many factors including its ease of use and adaptability to different devices. However, it also poses some challenges and problems that need to be addressed and discussed. Taking this into consideration ECSM 2017 seeks to establish a home for researchers and practitioners with a wide range of approaches to engaging with the impact, use and potential of social media across disciplines.
