I think its nice and awesome if youtubers like: Gdog, RedEagle, Athena Shy, Mudkip, Space_Fetus, Ed, and other more including me...I think, should have this feature :3
Because I was thinking if people/youtubers will have this tag people around in places will see them saying "He is a Youtuber, lets check his channel" then comes to those youtubers, then asks "what's your channel name" (sounds mental)
I suggested this just to help small youtube channel contents like mine grow bigger, only cubic castles youtuber should be approved and must have you know an amount of uploaded cubic castles videos.
As Lucaaa suggested: I think they should surpass 1,000 Subscribers!
Devs please add!
