Discord unfortunately “just works”. It’s simple for people to add someone, type to them, call them voice or video, stream their screen. I don’t think anything else does this as well as Discord, so it’s borderline impossible to convince anyone who isn’t a nerd to try some new option. Discord need to do a major fuckup to start an exodus.

If Teamspeak didn’t sit on it’s ass for a decade, we all would probably still be using that.
