In this paper, we investigate the concept and definition of Social Network Service (SNS). We present the political side of the Tunisian Jasumin Revolution, certification election photo, and Obama campaign as SNS use cases. We also evaluate SNS as the role of the election of public sphere. Moreover, we attempt to discover the prerequisites of SNS. Facebook and Twitter are examples of SNS where personal opinion is made publicly and the networking feature has a spread chain. This feature allows a sense that SNS functionality, as the policy for the election, shows the public sphere.
However, due to the limitations for political discourse, the political topic of Twitter, and word count limited to 140 characters, it is not possible for any serious discussion to take place. SNS is a hub for an exchange of communication with others like themselves and with those who have political affiliations, As made public sphere as fragmented appearance will seem. In the progress of the actual content, SNS has a limitation of political discourse through a lack of analysis on political contents. As described above, SNS has some disadvantages in the election public sphere but has a high frequency of access, high page views, and a huge variety of discussion. If we want to change SNS as an election public sphere, then, our people should have a higher sense of political responsibility and mission. As a result, our election culture can be transformed, focusing on policy-driven choices and not choices based on blood, regional, and alumni relationships.
