The list of people I interviewed at the World Economic Forum in Davos, Switzerland earlier this year is starting to look like more like a hit list than a VIP list. Two of them have been relieved of their current positions – MySpace CEO Owen Van Natta and now Ning CEO Gina Bianchini. If I were Jeremy Allaire, Max Levchin, Sheryl Sandberg or Evan Williams, I’d watch my back. They may be coming for you next.
