Data Dot Gov for Data

Data Dot Gov is a new government website  developed by the Federal CIO Council as an interagency Federal initiative and is hosted by the General Services Administration.  It's got a collection of government datasets and is encouraging users to suggest more datasets.  Browsing through the site provides links to a variety of information from government agencies and a number of informational tools like widgets for the FBI or airline on-time performance records. You can search the datasets by category, government agency, or both.
