The purpose of Data.gov is to increase public access to high value, machine readable datasets generated by the Executive Branch of the Federal Government. Although the initial launch of Data.gov provides a limited portion of the rich variety of Federal datasets presently available, we invite you to actively participate in shaping the future of Data.gov by suggesting additional datasets and site enhancements to provide seamless access and use of your Federal data. Visit today with us, but come back often. With your help, Data.gov will continue to grow and change in the weeks, months, and years ahead.

In addition, The Sunlight Foundation has launched the second Apps For America competition:

Apps for America is a special contest we're putting on this year to celebrate the release of Data.gov! We're doing it alongside Google, O'Reilly Media, and TechWeb and the winners will be announced at the Gov2.0 Expo Showcase in Washington, DC at the end of the Summer.
