This is a victory for government transparency, because it allows the website to get closer to its goal of providing "the public with information about how their tax dollars are spent."
I am also impressed by OMB's response. Robert Shea of OMB posted a comment on .gov Watch expressing his agreement and notifying me that he took corrective action.
OMB is clearly eager for USASpending.gov to be a success, so I will post a more thorough review including strengths and recommendations for the site in the future.
In the meantime, please explore the site and find ways to take advantage of its open API into the government budget. I am eager to follow USASpending.gov to see what happens when the government successfully embraces Web 2.0 technologies.
