I love Keybase. I have it installed in all of my devices.

Good

good app

Ok

Great extension from an awesome project

it's not the easiest to use, but well worth it after the proofs are made and keybase client is intstalled. peace of mind from using the certificates and pgp keys is very reassuring.

Works as expected, easy to use: install and forget. Been using it for months, don't plan to stop using it.
Tested on: HN, Reddit, GitHub

Works great

The button for sending messages on supported websites does not look intrusive. It blends in well with the style of the existing websites.

Makes messaging Keybase users much easier.
