I think allowing the new streamers to be featured on the main page would help them grow their communities faster, I would like to see twitch showcase some of the newer streamers that haven't got many views, maybe they could do it so that when you are searching in a specific category there's random new streamers scattered in with the regular much bigger channels, I would hope by doing this it will give them some exposure and allow them to grow as a channel
just an idea but thought I would mention it
