Sites like Facebook, LinkedIn, Youtube, Twitter and blogs in general are primary concerned with social interaction, hence the “social” in media. Anything that can help improve communication in any context, but especially in a business environment, is more than welcome.
Within the world of projects bad communication is traditionally the number one project killer. Problems all ready occur in an setting where team members and stakeholders are in one building, speaking the same language. The use of virtual, distributed teams has only increased the challenges in the communication department.
Putting home movies on YouTube is not going to solve all these issues. But the way these tools are constructed enable improved communication when face-to-face interaction is not feasible.
