I'm new with it myself, but I think part of what's being described is the option you have, when you have a Keybase account and the Keybase browser plugin and you're logged into a third party system (such as Fbook), of clicking on a Keybase icon for a given user and sending an e2e encrypted message from your Keybase account to theirs (even where they don't have one yet--if they make one later and associate it with their account on the third-party service, they will then unlock access to the message).

Ah hah, this seems to be the answer then. Thanks!

I like that idea of encoding before it hits FB/etc. Though, the level of security provided by a browser plugin makes me a bit nervous. Not an educated nervousness mind you.. I just tend to not trust them, and how well sandboxed they are, etc. It's the reason I also don't use browser plugins for password management.
