Am I taking crazy pills? Discord and Slack suck just as much imo. They are all a shitty web app repackaged for the desktop. And they are all fine, barely anything to chose betweem them. Teams is probably the best as the calendar integration with outlook and hosting ad-hoc drop in meetings in a room is good, no really, the virtual office is fantastic for pairing and team work.

IM peaked with IRC though, the simplicity was excellent, Matrix the closest thing to it imo. I do wish more stuff integrated with it to offer the same business experience as teams
