I have been fascinated to read about the various open government and Web 2.0 government efforts in the US and UK. The UK has the interesting They Work For You; information on MPs and their actions. Open Secrets is a great American project likewise dedicated to providing information about elected officials.
I can see a future where archives deliver new services through databases, automatically post all Freedom of Information / Access to Information responses online and I look forward to that day. The existing service model is only going to get more and more difficult to explain. Even though archives are generally perceived as being concerned with the past, the only way to thrive in the future is to build out new services like this. Maybe databases of the type suggested here wouldn't work, but let's get some innovation happening!
