We're definitely on the leading edge of the "next generation" of the social Internet, as well as the way we handle financial issues.

The "gaping hole" remains commercial use cases; the ability to shop via blockchain/crypto venues.

As for the logging in issue, seems to me the blockchain space is ripe for someone to develop some kind of cross-chain standardized "ChainID" or "ChainPassport" that could serve as the blockchain version of "log in with Facebook/Google."
