I was initially skeptical of Keybase, but I was happy to see the comments on HN of letting people use keybase without installing the CLI client were listened to. Seeing how many of my friends are on keybase now, that never had gpg setup before, I can't help but think it's filling a need that's otherwise unserved.

A lot of people are doing it this way: a GPG user can join Keybase via the website, without installing any Keybase client. When it comes time to prove something with their private key (say, their twitter account), the site shows them what to do, using bash/GPG/cURL.

It's pretty straightforward if you already have a key pair / GPG installed. There's no Keybase software to run, and the site basically acts like a todo list / tutorial.
