Social networks in Internet (SNI) have become a remarkable info-communicational space, validating social changes potentialized by telecommunication networks and mobile content access, as pointed out by actual researchers and scholars. Information science studies focusing the role of the information users in the Web 2.0 context need a cognitive and social approach. Based on this fact, this paper aims to explore the theoretical premises of the triad: Informational literacy, Profile and Potential Assessment and SNI. This work also sought to reflect about SNI from the media convergence approach, based on Jenkins concepts over media culture convergence aiming to contribute for future researches about personality aspects of the user and its influences on their informational behavior. For these purposes, a literature review was conducted, applying an exploratory methodology, which aggregates data about Internet usage in Brazil and Portugal. In the context of SNI, the initial question that arises is: Do those twenty dimensions of Profile and Potential Assessment relate to informational competence? The results provided by the theoretical research will serve as a base for a Doctorate project in the Information Science area
