Here's an interesting note on NPR relating to a private company that is aggregating the same data.
http://recovery.com/
"When Congress approved the stimulus bill, it made a point of setting up a Web site called Recovery.gov to allow citizens to track all those billions in spending. But if you've gone looking for it, you might have stumbled across another, very similarly named site, Recovery.com.
The dot-com version is not run by the government, but it also tracks the stimulus -- and much of its information is more up to date. In fact, it has spending information that the government won't have until October, and its data provide a sneak peak into how the stimulus spending is going.
The site is run by Onvia, a Seattle company that collects and sells data on government procurement. Whatever the layer of government -- whether state, county, school district or local water board -- Onvia wants to know what's being purchased."
