Joi Ito: Key technologies for the next generation of tools (and people)

WARNING: Mernit gets geeky wit’it here:
Joi Ito describes the Key Technologies, aka behaviors emerging from today’s new tool sets:
Creating and managing identities while protecting privacy
Creating and managing networks of friends and trust
Searching metadata and creating context for metadata
Design and interface for publishing and viewing micro-content
Syndication standards and technologies
Network infrastructure to enable location and mobility
Technologies to move and share micro-content, especially as it grows larger
Web services that interact with micro-content and the physical world such as photo printing, purchasing of real world products, connecting people, etc.

Great ideas, now how do we build interoperability and make these tools more widely available, aka build business modesl around them?
