Or you can look at the matching username on GitHub ( https://github.com/CydeWeys ) and see that I'm a member of the Google org and owner of the Nomulus repo ( https://github.com/google/nomulus/graphs/contributors ), the software running our TLD registry and which was announced here: https://opensource.googleblog.com/2016/10/introducing-nomulu...
Or I could just dig out my GPG key and sign a message.
So I respect your healthy skepticism, but I promise I'm really me, and not just someone pretending to be me! And I'll also note that, in all my time on HN, I've never once seen someone pretending to be anyone they weren't, at least not on seasoned accounts like mine. You can go back through my 5 years of comments on here, and every time I say I'm a specific person out there in the real world, it's always the same consistent person.
Not disputing your account in any way, but please don't propagate the widespread myth that only people who own an email address can send from that email address. If you wanted to use your well-known email address as authentication, you'd need to offer to reply to a mail sent to that address.
Though, admittedly, it would be easier for a layman to verify ability to reply to an email than to verify all those features, so point taken.
