The Open Government campaign will produce (and require) a tsunami of open data -- data produced by the government, data providing oversight, data informing policy making. But even once the data is free in principle, many barriers remain. Infochimps.org aims to bridge them. We're building a site where you can find any dataset in the world; share data, or put it back better than you found it; and connect the datasets, to each other and to the world.
