I can advertise my friends to follow my oshi's twitch, but it doesn't help him at this point. we need viewers who watches his streams. how do we hunt actual viewers?

honestly, his stream is pretty long. we can't require one viewer to see his whole stream every day. (i wish we could tho) so making more casual viewers or lurkers helps him I think. we need just number. wow what a mean term lol. actually not, we want more chatters too
