It is difficult to tell what the ultimate impact of these technologies will be for Iran. Nor is there any proof publicly available to support the claim that the vote was rigged in Mr Ahmadinejad’s favour. But the regime’s reaction to both the accusations of foul play and to the young people who demonstrated both in the streets and on the internet, is telling. As hard as a government tries to stifle dissenting voices, those voices will only try harder to be heard, and there is little that Iran can do to stop them. Technology always seems to be one step ahead of the censors.
