    1. not producing goods for consumption. Not centralized.
    2. open teams.
    3. Mashability -- reuse.
    4. conflicting, unknowable requirements -- discover by doing, emergent. Continuous evolution.
    5. Focus on operations. Start with a working system and aim for no downtime.
    6. Sufficient correctness. Perpetual Beta.
    7. Unstable resources -- many parallel prosumers.
    8. prosumer::= produce & consumer.
    9. Emergent behavior. Nondeterministic.

  6. metropolis_model::onion=kernel+periphery+masses.
  7. principles:
    1. crowd management>project management.
    2. promotion through ranks, attracting developers, meritocracy.
    3. split kernel services from peripheral services.
    4. pernipheral work is done by crowdsourcing, kernel by higher ranked developers.
    5. ubiquitous operations even as it evolves.

  8. implications: no phases, align business to crowd, not control but lead, tutorials and examples, usability. Requirements come from the periphery, forums help but can be shortcircuited. Architecture vital core. Small modular kernel. Tools for Testing, bug reporting and tracking. Flexible delivery. High availability.
