Nice, anyone used mattermost yet?
I have accounts on two instances, but I find it difficult to use due to requiring yet another app and multiple logins.
It’s not great. I like rocket.chat for centralized chat over Mattermost, but I like Matrix or even IRC (for public chats only) over either one.
Keybase is unfortunate because it’s highly centralized, but at least it’s totally end-to-end encrypted.
