From hardware and hardwires to smartphones and social, technology wants to connect. It's almost a native property of technology and especially software businesses, which is why network effects matter. "It was endemic to these technologies that they wanted to become connected and once connected, they become networks and once networks, they become network effects. Other products like cars or toasters or houses or whatever, aren't natively connected physically or through information sharing," observes James Currier.
