Communication mediated by technological devices promotes significant changes in democratic action and experience. Among the various changes incorporated into daily life are the new requirements of the informational dimension of public powers via digital network, which includes public communication. The objective of this study was to identify the theoretical and practical assumptions of Public Communication and the interference relations of the reticular communication in this process, with a view to reflect on the role and responsibility of the portals of the state governments, in the quality of the relationship and dialogue between the state and the citizen. As a methodology, following a bibliographic review of the thematic axes - Public Communication and Reticular Communication - a sample of portals of executive powers was observed in five regions of Brazil, in order to perceive the type of information conveyed, the establishment of interactive environments, the possibility of concrete transactions between government and citizens in these channels, the integration of services, the levels of information made available and the content analysis of some non-permanent sections. As a result, it was observed that the public communication present in the portals is little used as an instrument for expanding citizen experience. What is found is the provision of information of an institutional nature and of service rendering, since there are no dialog spaces for effective user participation in the observed portals.
