Me and like two other people talk on the discord, it's even more low key than here somehow.
I still have no idea what discord is but it seems to be more and more relevant these days. Is it like an IRC channel with voice communication on?
Discord is a skype-teamspeak like software that gamers are using more and more for collaborating (like Slack or IRC). It's run on a variety of devices (phones, computers) - allowing you to use voice with minimal setup involved.
It took a shit on Skype and is pretty much the de-facto these days for Twitch or other communities (Speedrun, etc)
