Over a period of time I have set out to bring the AIESEC network on LinkedIn together, using my own account as a central hub so that disparate clusters of AIESECers could find each other via the reduction in degrees of separation that linking though my account offered. Once the ball was rolling, the momentum has carried it through to now reach 2000 connections. It's been a pretty passive process that has taken only minimal effort - I drafted up an email describing my goal of bringing together the AIESECers on LinkedIn and how people could find others and use LinkedIn networking to their advantage, and then used the 'find colleagues' function every few weeks to find AIESECers in my newly expanded network or AIESECers that had joined LinkedIn recently, and sent them the email with an invitation to connect. I only actually know perhaps 50 of the connections, but that is not the point. The point was to connect to many others and thus draw together the AIESEC network, reducing the number of degrees of separation and allowing people to find each other. For others, yes, limiting your network to only those you know is a good idea. It is only a small thing, but hopefully it adds value to the AIESEC network, where members and alumni can find and get in touch with others with greater ease than had been the case.
