That’s interesting since you were already using slack, did you just switch due to network effect or are there additional features in discord?

Can it do drop in/drop out VoIP rooms like mumble?

Discord was originally a replacement for teamspeak/mumble and it’s how most people I actually know still use it. It was “nice” because you didn’t need to set up your own server. Using it as a replacement for irc came later. Image support in chats is nice, but I really only use it for the voip chat rooms.
