I mentioned Keybase's use of DID's in another comment in this thread. They've done a great job of demonstrating how a fairly non-technical user can generate their own PGP keys and cross reference these keys to various social identities and attestations. The records for each user's attestations and identity claims are written to the bitcoin blockchain, which gives users the ability to continue use of these identity claims, even if Keybase were to cease existing. Blockstack's identity model has some similar features, and in general, I've found the successful use of DID's to be blockchain agnostic, which is (IMHO) the way it should be.
