Laying Down the Law
Those open and sharing memes are spreading like wildfire in the most surprising places - like law, for example. In the US, there are two new important projects to place legal decisions online, freely available to all. There's Carl Malamud's database of legal opionions, and Tim Wu's AltLaw project.
But the thing that interested me most was a comment to the announcement of latter, which pointed out that that these US-based efforts are actually trailing equivalent moves elsewhere. The excellent site World Legal Information Institute has links to over a dozen of them. Shame on me for not discovering them sooner.
