Works smoothly and well. Good to know if someone has a Keybase profile or not from Twitter.

Nice approach! Will implement this.

A more convenient way to share encrypted messages or lookup someone on keybase, saves me the effort of copy/pasting usernames into the app. Also works as a reminder for myself to use keybase more often. Great job guys, and thanks for making it a webextension and open-source!

-- And I just found the setting to query profiles passively, neat.
