I've written in the past--whether it was about IBM's Smarter Cities Challenge or City Forward projects--about the different ways that cities can serve as laboratories of government and how cool it is that these projects can be part of this process. Given their size and immediacy in our lives, they are the level of government we are most intimate with. You may think state and national government is more exciting; still, nothing comes close to the city in terms of its impact on our day to day lives, and as they are more immediate, we can also have a much greater impact on them.
