I like Marc Zuckerberg's letter included in the Facebook IPO registration document : after a 1 page description of the Hacker Way, he has a full paragraph on his current and expected impact on governments!
(bolding of text is mine, not Marc's)
We hope to change how people relate to their governments and social institutions.
We believe building tools to help people share can bring a more honest and transparent dialogue around government that could lead to more direct empowerment of people, more accountability for officials and better solutions to some of the biggest problems of our time.
By giving people the power to share, we are starting to see people make their voices heard on a different scale from what has historically been possible. These voices will increase in number and volume. They cannot be ignored. Over time, we expect governments will become more responsive to issues and concerns raised directly by all their people rather than through intermediaries controlled by a select few.
Through this process, we believe that leaders will emerge across all countries who are pro-internet and fight for the rights of their people, including the right to share what they want and the right to access all information that people want to share with them.
Finally, as more of the economy moves towards higher-quality products that are personalized, we also expect to see the emergence of new services that are social by design to address the large worldwide problems we face in job creation, education and health care. We look forward to doing what we can to help this progress.
