Want to know where your US Tax Dollar is being spent?

Vivek Kundra, the federal chief information officer, on Tuesday announced a new Web site designed to track more than $70 billion in government information technology spending, showing all contracts held by major firms within every agency.

The revamped site, USAspending.gov, was launched early this morning, and Kundra unveiled it at the Personal Democracy Forum conference on technology and politics. The site shows detailed information about whether IT contracts are being monitored and budgets being met.

The site is the latest effort by Kundra and the Office of Management and Budget to make data about the government's projects and performance visible to the public. Citizens and Web developers can parse the data, combine it with other data sets and publish the results on Web feeds or their Facebook profiles. The data also show which contracts were won through a competitive process or in a no-bid method, which has been criticized by good-government advocates for excluding firms from business opportunities. Each prime contractor is listed as well as the status of that project; sub-contractors are not yet shown on the site.
