Having the good sense to set up a system that can create Ubuntu and let it work is a kind of vision. I vaguely recall something about this being how Steve Jobs worked: he created a system where people could work on ideas, and he only acted as the gatekeeper who kept the bad ideas from reaching the market.
Yes, Shuttleworth has good leadership skills and has pushed an agenda all these years, not to mention putting quite a few $million where his mouth was.
Do you think Jobs would have allowed a MacOs X update to badly break the way MS Office worked?
