@mentions could include groups/teams, I guess. Not sure about Braid but they are a thing in slack.

I think a conversation-first comms platform is a brilliant idea (though not sure this fits Braid). Instead of channels that can languish and/or have multiple conversations all jumbled up, you get a new window for a new conversation, even if it's the same group of people. With easy searching and archiving I think it could be great. If it isn't a thing in Braid or wherever else maybe I should shut my mouth and start a product
