Oh man a video WT study would be horrible. Very boring. I hated that WT study each week at bethel.
I thought about the split talk just once a month so the GB could show their face and power but still maintain a bit of mystery. But, you're right that they are egocentric and probably wouldn't want to share the stage.
My spouse and some of her dub friends love the fact that the GB is more public and out there. They feel it makes them so much more human and accessible. They also love how funny the GB members are and how down to earth they sound when giving parts. [insert puking icon here]
