This single sign-on business makes me nervous. Microsoft is being a little forceful with its single sign-on. I would not doubt that they enforce SSO a little more with Microsoft Blue. Why do you'all think the giants are moving us toward SSO and free storage. "Free Cheese in a Mousetrap", they will mine and massage your web travels and even the use of your computer and sell the statistical data. Otherwise, why so anxious to buy out a 20 person firm and pull a Microsoft. The giants want to control the SSO market; next step, only the giant's Servers will handle the SSO to the Cloud. There has to be big dollars in guarding the cloud gates. But, maybe I am just guessing. I do not really know enough to get ahead of them on the chessboard. What do you'all think ?
