Twitch Roulette or a Surprise me mode.
Somthing kinda like chatroulette maybe? Or a surprise me button.
Sometimes I just want to see something new. But trying to browse through so many channels can be overwhelming and I just end up scrolling and scrolling never really go in the the channels.
It would give new streamers a chance too I think.
I actually just posted this myself! Such a great idea I do hope they implement it!
