Discord is a voice, video, and text chat service initially designed for gaming communities but later expanding to study groups, school classes, and others. It uses a channel-based navigation system similar to Slack and is the primary form of community building for streamers outside the stream itself.
Many streamers have their own Discord servers for their viewers to communicate more closely with the streamer (than other social media platforms at least), and to find people with similar interests. They usually post their Discord links on a Twitch panel (see Channel Design).
According to our observations, streamers' Discord communities often reflect the streamer's content.
Mayuko ("hellomayuko") often posts videos on mental health in the technology industry, and encourages her viewers to take care of themselves. Discord members also heavily encourage this.
Longtime community members are usually extremely welcoming to newer members, and engaged often when we took part in conversation.
I (judgejudes) suddenly just jumped into this convo about nonfiction, and was treated as an equal, surprisingly.
There are different channels dedicated to different interests depending on a streamer's audience. Members often regularly use multiple channels.
hellomayuko's channel: She makes content about software engineering on Youtube, does co-working streams on stream, occasionally games, and enjoys stationary.
FeliciaDay's channels: She's a longtime content creator who streams gameplay. Note the "#parenting" channel: despite Twitch attracting younger audiences in general, a lot of her audience has grown up with her.
