Numerous times since January, the Obama administration has found that making promises about governmental transparency is a lot easier than actually making the government transparent. But Data.gov, the repository of data from federal agencies, is certainly a step in the right direction. Need to know the daily interest rates on Treasury bills in 2005? You can find it on Data.gov. Of course, the promise of the website lies not in personal use, but in what technologies can be developed using the data available, like FlyOnTime.us, which uses Data.gov statistics about flight times to find the least delayed flight between two cities. Programmers, let's make sure Obama keep his promises.
