The focus of CollectiveX is on the group, not the individual. Members of the group can interact via file sharing, messaging, calendaring and exchange of leads/contacts. It frankly answers to question that many social networks pose: Ok, we’re here, now what do we do? With CollectiveX, the entire point is to facilitate interactions among existing groups. As a member, you can be a part of as many groups as you like: boards, company teams, charities, whatever. For additional information, see my last post on CollectiveX, when it was just entering private beta. As I said before, CollectiveX is what LinkedIn should have been.
