My thoughts were that they wanted to see how many were watching so that they have a nice size audience when they go live with what they've got.
my camera is on my desk, steadily taking a video of my keys rn. Good theory, but no tripod. It's on the same surface as the keyboard.
None of the details matter yet anyway, this was just a test of the setup. The real live show is yet to come, and I'm sure they'll go live with it.
The lady pushing the stroller is cringing at the camera. Like she sees its reflection.
