TL;DR advice is to use email as your account ID method on various sites, and author's new service to 'verify' the accounts in a central place so people will know they are the same user between sites.

This isn't really decentralization is it?, it's a new kind of account linking which requires one to trust the central verification authority.

Maybe I'm missing something.

You wouldn't need to use your email as account id. The account id could even be completely random, as long as you manage to link back from that account to your key (in case of twitter, a tweet with the key fingerprint), anything works! Just add a link to that account to your key.

With regards to decentralization: keyoxide doesn't hold the proofs. Your key does. You can take your key to any verification system, whether it is keyoxide website or some CLI tool or an app, and have that verify the proofs. Yes, you do need to trust the service. But that's where the open source and hopefully one day, network effect comes into play. If enough knowledgeable people trust it and talk about it, then less-techy people might one day too.

In the end, what is important to note is this: keyoxide is just an implementation detail. If soon a different service becomes much more popular and used, the "decentralized identity proofs" ecosystem still wins! I would love to see apps get developed where anyone can at the press of a button verify online identities. That will be the next big milestone.
