Data.gov is one of my favorite new websites. I work in a job where data is vital for making recommendations and Data.gov is a valuable new tool that enables quick but powerful research. The website is a government resource with the purpose "to increase public access to high value, machine readable datasets generated by the Executive Branch of the Federal Government."
Governments are often a vital first resource of macro-economic data, and Data.gov takes that to the next level. This type of organization and openness is well worth the investment as it benefits the overall economy. If I can save 30 minutes a week (which is a very reasonable estimate) then others must be saving time as well. And as we all know: "time is money."
