As described on the Solid and Inrupt websites the new platform will allow users to have complete control over their information ‘pods’ (an acronym for “personal online data store”) — it is only they who will decide whether outside apps and sites will be granted access to it, and to what extent.
Unlike Facebook or Twitter where all user information ultimately resides in centralized data centers and servers under control of the companies, applications on Inrupt will compete for users based on the services they can offer, and only the users can grant these apps “views” into their data, making personal data instantly portable between similar applications.
@yahananxie I know of them and to some extent their tech. But no never hosted it.
