Zaheeruddin AsifInstitute of Business Administration Karachi zuasif@gmail.com Web 2.0 has great potential to serve as a public sphere (Habermas, 1974;Habermas, 1989) -a distributed arena of voices where all who want to do so can participate. A well-functioning public sphere is important for pluralistic decision-making at many levels, ranging from small organizations to society at large. In this paper, we analyze the capability of the blogosphere in its current form to support such a role. This analysis leads to the identification of the principal issues that prevent the blogosphere from realizing its full potential as a public sphere. Most significantly, we propose that the sheer volume of content overwhelms blog readers, forcing them to restrict themselves to only a small subset of valuable content. This ultimately reduces their level of informedness. Based on past research on managing discourse, we propose four design artifacts that would alleviate these issues: a communal repository, textual clustering, visual cues, and a participation facility for blog users. We present a prototype system, called FeedWiz, which implements several of these design artifacts. Based on this initial design, we formulate a research agenda for the creation of new tools that effectively harness the potential of the growing body of user-generated content in the blogosphere and beyond.
WEB 2.0 AND THE PERILS OF SELF-PUBLISHINGWeb-based collaborative applications commonly known as "Web 2.0" (O'Reilly, 2005) have been changing the way individuals interact with each other and the public at large. These applications have changed the communication paradigm from a one-to-many to a many-to-many format. Web 2.0 , at its core, is a mechanism for self-publishing user-generated content (Cayzer, 2004), which can be in various forms ranging from online video (e.g., YouTube, Google Video, MetaCafe) to text-based content (e.g., Blogger.com, WordPress, Wikipedia). The intended audience of information shared in Web 2.0 also varies greatly, from narrowly focused content to information intended for a much broader audience. For example, social networking sites such as Facebook and MySpace provide mechanisms for users to share information about themselves with unique and limited networks of individuals. In addition to this kind of "narrowcasting," using Web 2.0 to broadcast to a broader audience is also common. Users of Twitter can publish brief, public "microblog" entries regarding what they are doing at any point in time. Another example is user-created posts sharing reactions to news stories on CNN.com.Within its many applications, one of the most visible and established components of Web 2.0 is the weblog (or "blog"). The term "blog" is commonly used to describe a web site where an individual (typically the owner or the "main author" of the site) or a group of individuals write about a variety of topics such as the details of their daily lives or their reactions to ongoing world events. New technologies have made it very easy for users of all skill l...
