One thing that's curiously missing from Data.gov is an RSS feed for new data feeds. Sort of shockingly, and glaringly left out. We were disappointed, and didn't want to wait. Scraping here is such an easy thing to do that we decided to just build our own. Sunlight Labs' James Turk did it, and it's handy. Here's the feed and here's the source that makes the feed. This should be useful to anyone who wants to see what new stuff is coming out of Data.gov.
