Google is talking about how Google+ can integrate existing Google apps to deliver an enterprise collaboration or work media product. Remember Wave? It never caught on partly because it lacked a single killer use case, and Google, without much of a direct sales or support organization to service enterprise customers, couldn’t create one for them. This time Google is taking the approach of “cobble together these things you’re already using,” and offering some simple admin tools to help. I’ve praised the bolt-on approach for Yammer and other work media tools, and yet I think specialists are wise to build suites of social enterprise solutions. Google feels like it might be caught somewhere in the middle.
