I'm way back in my reading of this thread am just trying to catch up.
The thing with the Q's main demographic, though, is that everyone eventually ages into it, even as a portion always dies out. Once folks retire, they have more time and inclination to channel surf. Not everyone is an "active senior" like those portrayed in TV commercials, so the Q is likely to catch their eye sooner or later.
Though I agree that the "talk show" format is annoying. The Q's strength is to be able to provide much more information about products and demonstrate them in real time. I like during some of the tech shows how they answer the questions that are being asked on social media regarding particulars about the item being presented. That immediate feedback is one of the things that they have over the average website.
