For many oppositional movements, the Internet, while providing the opportunity to distribute information more quickly and cheaper, may have actually made their struggle more difficult in the long run.

As Barbara Streisand discovered, adopting a militaristic posture against a tech-savvy mob of civil libertarians is not going to be of much help: Many of them run their own servers and blogs - and have thousands of friends on their social networks - so overzealous attempts to silence them only lead to wider dissemination of sensitive information.

I think governments will increasingly be tempted to rely on Silicon Valley to solve problems like obesity or climate change because Silicon Valley runs the information infrastructure through which we consume information.

When someone at the State Department proclaims Facebook to be the most organic tool for promoting democracy the world has ever seen - that's a direct quote - it may help in the short run by getting more people onto Facebook by making it more popular with dissidents.

Once Google is selected to run the infrastructure on which we are changing the world, Google will be there for ever. Democratic accountability will not be prevalent. You cannot file a public information request about Google.
