Bill Gates has stepped down from Microsoft's board
Satya Nadella is doing a terrific job leading Microsoft. Prior to his taking over, Microsoft was seen as a has-been. Today Microsoft is the most valuable company in the world once again (edit: AAPL is slightly ahead).Nevertheless, this is a sad day. If anyone has the ability--and credibility--to provide guidance to Nadella it is Bill Gates. With Gates gone (and Ballmer too) it is Nadella's Microsoft. That's not bad necessarily, but having Gates around as a backup was a good thing.
