The February 2011 Issue of the Association for Project Management's Project Magazine features an article with contribution by Maciver Project Services' Founder Lynne Maciver.
The article explores the use of social media for project managers including tools such as Twitter, Facebook, LinkedIn and YouTube. The reviewers concluded some tools were more useful than others.
"Our overall conclusion is that social media tools do have a place to support project managers. However certain tools may be of less use than others, and individual users will have their own preferences."
