>>415148The children thing is only speculation. "Chumbabbies" could be a silent admission of it, given that both Ame and Gura most likely know her viewer statistics, but it could've just been a meaningless jab at the chat.
But saying that a not-so-tiny portion of Gura's viewers don't actively watch other holos, is not farfetched at all. It's not to say that majority Gura fans are like this, but just by the virtue of the size of Gura's audience, and things like those unique chatter charts, it is likely that a Gura-only demographic exists.
It's not bad, and it's expected given Gura's audience size.
It happens with every holo to a certain degree. Ame playing a buff game brings out people who don't even know Big Red Heart, so any time the audience is huge, it's likely that there are many people who don't know much about other holos.
