While I like the photo, and the likeness of Muammar is striking - the image perpetuates the misguided notion that the internet caused these revolutions.
While media attention may help to encourage these revolutionaries, it is their actions, and their sacrifices that are responsible, so I think the infectious idea of freedom, and the perseverance of the people involved are much more frightening to a dictator than the internet.
It's merely a tool. It worked for some, but not the Iranians.... yet.
