A collaborative blog is a type of weblog which publishes posts written by multiple users. The majority of high profile collaborative blogs are based around a single uniting theme, such as politics or technology.
While the traditional popular (and rather insulting) view of the weblog is that of the lone blogger hunched over his or her keyboard in their parents' basement, in recent years the blogosphere has seen the emergence and growing popularity of more collaborative efforts, often set up by already established bloggers wishing to pool time and resources to both reduce the pressure of maintaining a popular website and to attract a larger readership.
