That can be difficult to do when you have your stream open. Well, now you can hide it (sorta). Twitch released a small new feature that allows you to hide your viewer count on your Dashboard. Simply click the red person symbol to toggle between displaying your viewer count and hiding it. There are a few caveats with this feature.
Many Twitch viewers are used to just joining a stream and not having any direct communication with the streamer, so this can really help you start getting a few regulars so you are no longer streaming to 0 viewers on Twitch. Hope This Helps You Get More Viewers on Twitch and Happy Streaming!
