Yep. This sounds like the latest Pied Piper scheme.
Solid is a platform, built using the existing web. It gives every user a choice about where data is stored, which specific people and groups can access select elements, and which apps you use.
It allows you, your family and colleagues, to link and share data with anyone. It allows people to look at the same data with different apps at the same time.
Imagine if all your current apps talked to each other, collaborating and conceiving ways to enrich and streamline your personal life and business objectives? Thats the kind of innovation, intelligence and creativity Solid apps will generate.
With Solid, you will have far more personal agency over data - you decide which apps can access it.
