This interesting technology, see article attached, positions itself as a first in corporats social networking. It is interesting conceptually since contrary to social networks where one selects his "friends" this social network approaches searches, like Google, all documents and relationships in order to map the social networks and to identify the right person one needs to talk to.It is in between KM and social networking and mapping.
One of the salient features in this concept (not new but developing fast) is the recognition of the fact that within a corporation one has colleagues and not friends. For me it is the most important differences between any public social networks and corporate social networks.
