Twitter, a social networking application based on the concept of microblogging, has grown rapidly since its 2006 inception, and now claims over 100 million users. In direct opposition to bloated social networking applications that overwhelm their users with functionality, Twitter users log on for a single reason: to post an update (often called a tweet) and to read other’s updates. Furthermore, a strict 140-character restriction imposes brevity of updates and can serve as a vehicle for creativity. When faced with such a low limit, users are forced to concisely state whatever information they would like to get across. This, in turn, makes it easier for others to read others’ tweets without losing attention. This streamlined functionality has been lauded by critics who appreciate the ability to use the application as much or as little as possible.
One of the most interesting features of Twitter is its implementation of “Trending Topics,” which is a real-time Top Ten list the site posts organizing the phrases most often contained in user tweets. The user can customize the list to be specific to a certain geographic region or allow the topics to be ranked worldwide. In this way, he or she has access to what are-in theory-the most interesting conversational topics in the world. The usage of trending topics to unite people from drastically different geographic regions by shared interest perfectly validates the idea of cultural citizenship.
