- In enterprise 2.0 the tools enable employee to employee communication, awareness and collaboration
- In the "social intranet" while employees do form communities, the primary focus is on the organization to employee communication customised by the "social" data shared by the employee.
- Enable collaboration in the process of making decisions - which is what some social business tools enable
- Enable serendipitous discovery of people with shared interests and help people to connect and engage with each other
Unfortunately for organizations that seek to keep a control on the conversations, they will choose the "social intranet" over collaboration, as they are scared of the network and people to people connections.
On a different note, it's always surprising to me that the decision of an organization to embrace "social" is taken by a single person :)
