The Shared Information Sphere: Blogs and their Impact on Journalism
Bloggers are the group of new information deliverers that so far has gained the most attention from journalists and in scholarly research (e.g. Lasica, 2003; Matheson, 2004; Reese et al. 2007; Wall, 2005). How many blogs there are on the web is not exactly measurable, with new ones created virtually every minute while others are abandoned yet still present on the web. Blog search engines such as Technorati try to keep track of their numbers and provide lists of blogs most read or quoted. As of April 2010, BlogScope, for example, an analysis tool for the blogosphere developed as part of a research project at the University of Toronto, was tracking more than 44.2 million blogs worldwide.
