The social networking site Linked In has launched a series of business applications which could be useful in fostering collaboration with the enterprise.
Linked In says the initial roll out "features productivity applications that range from gathering information that professionals around you are generating to enhancing your abilities to collaborate and communicate more effectively. You'll be able to work much more closely with your contacts on LinkedIn with tools such as file sharing, project management, business trips and many more." (Business trips? That was presumably before business trips became a victim of the credit crench!)

It seems like Company Buzz is the most likely to capture the imagination. Company Buzz shows you the twitter activity associated with your company. You can view tweets, trends, customise topics and share buzz with colleagues.
