> the constant CC'ing Isn't this exactly like adding/mentioning someone in a chat room? Problem is that in a chat room all communication is public and you're seeing/getting notified of every single small message. This is hugely inefficient. For e-mails, one can define filters to park e-mails where you're on CC to read later. You don't have this flexibility with Chat/Slack - the tool defines much more how you should be reading the incoming stream of messages.
