Almost 400,000 people on Facebook have shared an image of Bill Gates holding a photo of him holding a message: If you click that share link, I will give you $5,000. I always deliver, I mean, I brought you Windows XP, right? Clearly, no-one is going to receive any money for sharing the image. And chances are that the picture was meant as a joke, although it would have been funnier if the message hadnt said Windows Vista rather than Windows XP.”]
