nsf recovery stimulus spend rss transparency
The NSF has put up a "recovery" page for the stimulus bill: http://www.nsf.gov/recovery. Interestingly it appears that there is an link to an rss feed for "weekly reports." These appear to be excel files of the spending done by the NSF under the stimulus act as of that week (so far nada has been spent.)
Cool, now we can set up a betting pool for spending amounts as of a given date :)
