I love this. At a glance, here are some dynamics this reveals:

1. You can share a channel with a friend and know that they see the same thing as you. What's on at 5:03pm on channel 4 is the same for everyone.

2. The decision of what to watch is topical and greatly simplified. It extracts the decisions from "the algorithm" and gives you agency again.

3. There's a lot of stuff you never see on Youtube's recommendations because the algorithm doesn't show you those videos. Ever.
