Does anyone of you have a https://keybase.io invitation code I could use? I'm curious
No, they aren't joking: the Tor .onion is a nice touch too!
It's become a minor thing in the infosec community. Whether it actually catches on or becomes truly useful is quite another matter.
You don't seem to have dropped any contact details, which is fair enough considering where we are. I'll do the next best thing here: my PGP fingerprint is 74EB 1642 9904 69C3 6C5A 20C0 EC84 8ED9 168B 6B7A. You can find me in a moment from that: if you send me an encrypted email, I'll send you back an invite. OK?
