Abstract
A large number of Social Media Management Systems (SMMS) have been developed to maintain multiple accounts over different online social networks. Each system has pros and cons and can be more or less useful depending on its features and cost. This paper presents a state of the art of the existing platforms for managing online social networks. The state of the art is structured with a framework that guides the analysis of each social media management system according to its own characteristics and the characteristics of the online social media content that the system helps to manage. The state of the art has two outcomes: a comparative analysis of the presented SMMS and a collection of requirements for what is believed to constitute a "good" system. (C) 2015 The Authors.
