It solves the problem of needing to make and remember a username/password on every site you use, it solves the problem of password hashes being leaked when a site gets compromised, it solves the problem of not being able to know that hihihihi1234 on hackernews is the same person as hihihihi1234 on lobste.rs, and it solves the problem of trying to make an account on a website only for your typical username to be taken already

There can still only be one twitch.tv/spivak.
