Advantages of Collaborative Blogs

For Bloggers

In recent years the blogosphere has seen the emergence of many new Invite Only collaborative blogs, each accepting contributions from a group of established bloggers. While it may be unfair to ascribe this trend to any particular cause it is often the case that the pressures of maintaining a popular individual blog for an extended period of time can become too great, leading the successful blogger to naturally tend towards a lower pressure collaborative effort.

On well-known example of this phenomenon can be found at Protein Wisdom, a popular blog written by surreal conservative Jeff Goldstein. A much publicised incident in which Goldstein was harassed by University of Arizona adjunct lecturer Deborah Frisch - combined with various other real-life obligations - led Goldstein to retool Protein Wisdom as a collaborative site frequented by a number of guest posters while Goldstein partially withdrew^[4]. Today Goldstein blogs both at Protein Wisdom and the high profile collaborative blog Pajamas Media.

Collaborative blogs (especially of the Open Invite variety) allow those without their own personal site (or those with poorly-trafficked sites) the opportunity to present their opinions to a much larger audience than they would typically have access.

For Readers

A primary advantage for the readers of collaborative blogs is the simple fact that a collaborative effort usually make for a moreregularly updated site. It is not unusual to find collaborative weblogs publishing new material 24 hours a day, allowing readers the opportunity to read new material on an almost constant basis.
