Social Networks in the Enterprise

Information Week article on how the enterprise can best use social networks.  I was involved with the examination of social networks to get things done.  Part of the argument was that new hires were coming in with the expectation that social interaction was already part of their day to day work.  But it also led to some lack of focus.  So how to you integrate social networks to the tasks at hand?  I am still supportive of selective and directed social networking use.  Its a means of easy and group connection and interactive.  A good examination of some of the direction.
