- The blogosphere is made up of all blogs and their interconnections. The term implies that blogs exist together as a connected community (or as a collection of connected communities) or as a social network in which everyday authors can publish their opinions. Since the term has been coined, it has been referenced in a number of media and is also used to refer to the Internet.

http://en.wikipedia.org/wiki/Blog#Community_and_cataloging
- The Blogosphere: The collective community of all blogs is known as the blogosphere. Since all blogs are on the internet by definition, they may be seen as interconnected and socially networked, through blogrolls, comments, linkbacks (refbacks, trackbacks or pingbacks) and backlinks. Discussions "in the blogosphere" are occasionally used by the media as a gauge of public opinion on various issues. Because new, untapped communities of bloggers and their readers can emerge in the space of a few years, Internet marketers pay close attention to "trends in the blogosphere".
