Transparency is generally a great idea, and the Transparency in Government Act 2008 seeks to make the US government as transparent as possible:

The draft legislation is an amalgamation of bills that have already been introduced, along with new provisions. If enacted, it would create historic changes in the way the executive and legislative branches provide information to the public, and Sunlight believes it would foster a better and more complete understanding by the public of how the government works.

You can comment on any section of the law. Nifty.
