Haven't seen these before thanks for sharing.

It's different from a reddit poll in two ways:

1) Artificial scarcity - like Wordle or a NYTimes cover photo, there's only one per day. This focuses attention to one topic at a time.

2) Before/after polling. The audience is polled initially and then asked if they've changed their mind after a while reading arguments. The winner is the debate that changes the most minds.
