Network is not the network in computer scince it is the people who connects and share the knowledge or atleast assert your idea. It is not possible to all that they just talk to everybody or they are very few frens but they are brilliant in creating the products, for such people VC funding and getting into their network is more usefull. And doing so you can get the pulse/need of the people and your ideas sharpens and you know you need to close the doors.
