Habermas described the Public Sphere as being “made up of private people gathered together as a public and articulating the needs of society with the state”. He explains that “through acts of assembly and dialogue, the public sphere generates opinions and attitudes which serve to affirm or challenge–therefore, to guide–the affairs of state” (Habermas, 1991) The public sphere is an intangible concept in which people gather to exchange thoughts, ideas and opinions. Obviously the public sphere has changed over time with new technologies and inventions to aid its formations. None more powerful than the invention of social media, which has brought with it another form of public sphere.
Blogs are websites, often maintained by an individual who consistently add entries which can be a personal diary of sorts or commentary or recent events and current affairs. Collectively blogs are referred to commonly as being a part of the Blogosphere. The term suggests that blogs exist together to form a connected community or as a social network where people can post their views and opinions. Similarly to Habermas’s Public Sphere they are both places where individuals share their knowledge and personal thoughts.
How ever it is vastly different as people are not face to face with one another and on many occasions do not even know the person they are communicating with. This is a very important aspect of the blogosphere and Twitter sphere as anonymity dramatically changes the way people interact with each other.
