The notification we SHOULD get when we get drops enabled for our channels. Personally i don't get any on twitch or by email, I find out eventually through my viewers every time.
I noticed this section in my affiliate settings today. Twitch enabled stream display ads by default! If you don't want to have them definitely check your ad settings.
Twitch should introduce more novel algorithms to Browse to make smaller streamers more discoverable. E.g.: an Upcoming Consistent sorting, which would prioritize streamers with small view count, but consistent streaming schedule. What do you think?
