It only works if American citizens get involved, and here's how to get involved; check out a new blog from the White House: Make Your Voice Heard:

Now through March 19th, the American people can make a difference by logging on to each agency’s open government page and making your voices heard. We hope you will assist us in this historic effort to bridge the gap between citizens and their government. It would be particularly helpful for you to provide specific suggestions for what agencies should include in required elements of their plans. These elements include a strategic action plan to improve transparency, as well as agency proposals to use technology platforms and other innovative methods (e.g., prizes and competition) to improve collaboration.
