There are a handful of technologists on the Time 100 list of most influential people, although interestingly Bill Gates is listed as half of Bill and Melinda for their work on malaria and world health, not as the man most responsible for making the computing world the way it is. Thus, he is a Leader and Revolutionary, along with Bush, Condi, McCain, Hillary and the Pope.
Tiime shows its with-it colors by picking from the tech world not Steve Jobs or Larry Ellison or Sergei and Larry (although a strong argument can be made for those two) but Jimmy Wales (thinker) and the Flickr Founders and Skype Guys (builders/titans).
This raises a question: Who are the most influential people in government IT? How about Massachusetts' former CIO, Peter Quinn (pictued), who moved the Bay State from Microsoft to ODF, before resigning. It's possible Quinn's courageous actions will start a groundswell of government movement towards open formats.
