Orbit's Twitch community integration, built by Michael Jolley, creates a new activity for chat messages, commands, subscriptions, raids, and cheers on a user's channel. It is always-on and adds activities immediately.
Twitch is a video live streaming service. While streaming viewers can live chat, follow, and subscribe to the creator's channel. Towards the end of streams, creators often 'raid' other channels bringing their audience to another livestream as they wrap up.
