Forrester's Koplowitz concurs. "Over the next few years, we'll see greater integration across these tools. Think about how messaging is integrated into Gmail -- you don't have to switch back and forth because they're all integrated together," he says, citing work that IBM (with Connections and Notes), Google (with Gmail and Gchat), Microsoft (with SharePoint and Yammer) and Facebook are doing.
"We'll have a new environment with new aspects of communication," Koplowitz predicts. "Today they're different tools, but in the next three to five years, they'll be integrated."
