The 3.0 technological scenario reflects the tsunami of data on the Web and, in this panorama, it is important to consider how information is organized in the interface of social network. In literature review, the work on social network analysis investigates the production of discursive practices and enunciations, behavior of members and distance learning. A lack of application of usability was perceived, as a tool to evaluate the organization of information in the navigation environment. This proposal addresses usability as a tool for the evaluation of information in the Amino application BR Readers community. The methodological approach has two stages. The first one is the application of the network interpretation script by Kadushin (2012), that involves the following categories: quality, nature of connection, intensity, popularity or centrality, named positions and relationships, and observed roles. The second one is the application of the guidelines of good practices of the Electronic Government Accessibility Model (eMAG) and involves the following guidelines: context and navigation, level of information, autonomy, errors, design, writing and consistency and familiarity. Results reveal that there are some usability requirements not included in the organization of the interface, such as the lack of intuitiveness and visual pollution, the organization of texts in blog posts and obstacles to visualize search commands and access the user profile.
