all social media (or any system) where you dont trust the entities that are holding your data are candidates for blockchain. With blockchain based databases you can have entities that store massive amounts of data encrypted, but they cant read it or access it. The blockchain controls access to it. The data itself doesnt need to be replicated, just the access control. This resolves the issue of very slow blockchain databases. The storage providers can charge the blockchain for storage and access. blockchain disintermediates access control, storage, and display. With open protocols for data, you could use any number of reader clients to access your (and other) data.
