One of many new things I've learned about reading boingboing.
Link to September 18 Shareable post, "Four Degrees of Sharing".
1. First degree. Cooperation + minimal planning.
Example: Borrowing and lending goods.
2. Second degree. Cooperation + more extensive planning.
Example: Neighborhood tool lending "library".
3. Third degree. Cooperation + extensive planning + infrastructure.
Example: Community-wide tool lending libraries.
4. Fourth degree. Cooperations + extensive planning + infrastructure + community-wide restructuring and mobilization.
Example. Expansion of public library systems to include lending of tools, equipment, and other goods.
