"Where users are able to determine the user-facing modules with which they can interact. Where users can determine which location or locations the information that these modules use are stored. Where users are able to customize their total Internet interaction and user experience, without third-party restrictions placed on how they can access, share, or move the content that they, themselves, have created. All this is Modular Innovation — innovation of many parts, or modules, that result in a much larger, cohesive whole for the user.
The components and products that enable this time of Modular Innovation knock down the encumbering walls. They allow for complete control of one’s own content, through the ability to integrate with other Innovative Modules (services & products), incorporating flexibility, portability, and facilitating the total customization, and self-determination of and by users with respect to how they interact with their personal creations and those of other individuals and companies."
