How can open collaboration be scaled up? From collaborative book-writing to planetary ingenuity gaps, there are tremendous opportunities to leverage open-source practices.

We'll talk about several specific challenges, increasing in scale from personal to planetary. Each challenge is a practical task for which better solutions really matter. Examples:

• "Collaboratively writing a book": How can dozens of people collaboratively write a top-notch book? For "parallelizable" books, how could we enable effective distributed editing and peer review while maintaining overall coherence?
• "Open-Source Scenario Planning": Scenarios and models are key tools to prepare for future possibilities. Can collectively generating and sharing models accelerate planning and help move public discourse beyond rhetoric?
• "Open Health": Despite huge amounts of raw biomedical information online, there are few open-source tools for diagnostic assistance, patient records, and preventive health support. What if a small fraction of public health budgets was redirected to open resources geared toward the public at large?
• "Macro Social Entrepreneurship": There's never been a time when forming distributed teams was as easy as today, yet the problems we face are also of unprecedented magnitude. How can we continue to scale up the effectiveness of citizen-led problem-solving?

We're hoping to share short interview clips from people who are already tackling these issues and—by identifying specific challenges and opportunities for tool building—to spark creative initiatives among the O'Reilly audience.
