How about adding a "Scan" button for small streamers to the front page that acts similarly to the scan button on a car radio. Press the button and Mixer randomly selects streamers with, for example, less than 15 or 20 viewers. You'll stay on that streamer for 5(?) minutes before it randomly selects another streamer. Could be a way to incorporate the "Up and Coming" Feature already available on Mixer?
Ideally, the source of streamers for this feature would be games with 20(?) or fewer congruent streamers streaming said game. This would, in theory, highlight both smaller streamers and "smaller" games and keep out larger games like Fortnite, PUBG, etc that already get plenty of exposure. Mixer could even add filters like certain platforms, genres, channel audience, language, Interactive, etc viewers can adjust before pressing the "Scan" button.
My ultimate goal is to expose smaller streamers and less streamed games to a wider audience. Right now unless someone is actively looking for a particular game, a smaller streamer is less likely to be noticed. A "Scan" button lets Mixer do some of the work versus an individual having to scroll through page after page of random streamers.
