My ten favorite social inventions:
1. The webocracy: The finest example of a self-organizing and non-partisan strategy so that every one can be in the know and have a say and so organizing the democratic world they value around them as they wish.
2. The bioregional natural guard: Former remnants of national governments (who are too obsolete to repair) combined with selected military units (converted to support the repair of the biosphere in homogeneous natural regions) are the next infrastructure of choice.
