Scoble's boss is leaving Microsoft for Skype:

I just couldn't go on being an evangelist for a gospel that I don't believe I can sing. I am returning to focus on what I enjoy most, building amazing things that make people happy, change lives, and make money. In this case Skype was a better place for me to do this and one that shares my core values and beliefs in how the future of both software and business will unfold.
