Bill Gates' passion has become his outstanding philanthropic work, mostly relating to global health initiatives, and today he said he'd leave his day to day management of MS over the next two years.

Although the future of Microsoft may be in question thanks to the rapidly changing online, open source and competitor environments, this is a great day for international development efforts.  

In addition to saving over a *million* people from tragic deaths due to disease, the Gates Foundation has brought an entrepreneurial, innovative approach to the development of global health solutions.   I'm thrilled that Gates – still a young whippersnapper – will devote his substantial intellectual and monetary resources to the world's greatest challenges.  Bravo Bill!
