Thanks. Yes, I do. There is a lot of work in the field of decentralized identity, but status is still far from a 'solved problem'. Work being done by Rebooting the Web of Trust [0] (see their github repo's) and Identity Foundation [1]. Besides Solid there's a bunch of interesting, related specs evolving like Verifiable Credentials [2], Self Sovereign Identity (I hope for impls without the blockchain).
