Microsoft’s Tom Rizzo:

In cancelling this group of social media-like services, it is clear that Google is not in tune with the market needs and does not have a product roadmap and clear vision for productivity for their business customers. The Microsoft Office team does. Our vision demonstrates a clear focus on what business customers are looking for, such as intuitive interfaces across a wide range of devices.Google releases experimental products and tracks adoption to determine whether to continue providing them. Its products are like spaghetti, Google throws them up against the wall to see if they stick.

Michael Gartenberg’s take on Twitter is classic. “pot to kettle, you’re black.”
