I use it entirely to offload identify verification to a 3rd party so that people, if they care, can be certain someone who has control of my private keys, who - with great probability - is me when I say it's me and sign a message. I also use it to show people the basics of "why encryption" and for certain technical security aspects as it makes it super easy to have them sign up and play around with it. Signing messages, verifying signatures, encrypting messages, the tradeoffs of storing your private key with Keybase (and why you shouldn't), etc. KBFS is also really, really, really awesome. It's a shame I haven't heard much about it since that (seemingly?) attempt at a pivot.
