Make a Browse page sorted by "Recently Went Live"
Make a page specifically to find streamers who recently went live, sorting by the newest being the most recent to go live.
To prevent exploiting by restarting the streams all the time, add a 1 day cool down on showing up on that page.
It'd be an easy way for people to find new streams, around the hours that they're usually around to watch Twitch. It'd be a good addition to the exposure of even small streamers.
