Microsoft's CEO Steve Ballmer (the one that came after Bill Gates) will be leaving his post as CEO within a year. As of right now it is unknown who will replace him. Steve Ballmer has been with Microsoft since the beginning and will be tough to replace. If they can't find anyone I would probably be available (if the price was right). Engadget has the news over here.
One thing's for sure: whoever steps into Ballmer's shoes is going to have bring some sweaty, screaming enthusiasm to Redmond. But whoever the John Thompson-chaired succession committee picks, we'll certainly miss keynote dances and chants of, "Developers! Developers! Developers!" when Steve Ballmer steps down from his job as the head of Microsoft some time within the next 12 months.
