The Twitch channel should raid other channels
Being new to twitch is very daunting, there is so much invisible content that you would never discover unless you knew it was there. Why don't you have a twitch channel that new users can join and the channel goes on a raid journey whereby those in the channel can be exposed to content they would otherwise not have seen, and on the way those who like the channels they visit on the journey can drop a follow or even subscribe or even jump onto the channel they find and like. Like a guided tour bus that you can get off when you see something you like. Having twitch raid your channel would be a real confidence booster for any streamer and it promotes the platform as well.
