"When we collaborate, we work jointly on an activity, toward a common goal," Byrne said. "When we network, it's really about connecting with others for its own sake – it's about the relationship. Also, this is about humanizing the digital experience. Much of our software, to date, has assumed we were autonomous robots working in a cube." Collaboration and networking can be very complementary – for example, networking often introduces people who will later become collaborators, he said.
What workers really want is an environment that allows them to switch smoothly between those two modes of interaction, Byrne said, but most products today are not equally strong in both. For example, Microsoft SharePoint is a strong (although not perfect) collaboration environment but a weak social networking tool. Yammer, in contrast, is almost all about social networking, even though it has expanded its features list, he said. "Yammer is fundamentally a microblogging program that happens to have a few other services."
