A recent few with varying degrees of promise and accomplishment, but all of interest:
- http://resource.org/ — and especially the PACER data in connection with http://www.recapthelaw.org/
- http://www.wolframalpha.com/ — swank on science, and I look forward to more social science data. The contents of the various editions of the Statistical Abstract of the United States would be a good next place to beef up coverage.
- http://www.data.gov/ — brilliant idea; more to realize.
- http://usaspending.gov/ — a public-friendly front-end for the authoritative Federal Procurement Data System (FPDS). FPDS data is available to the public as well at http://www.fpds.gov/
