Not just the architecture, but also the possible logistics of such an event. Who’d contact John Oliver’s PR team, for example. What about the scheduling? Also, while I think people here are good-natured enough that it might not be necessary, who’d be making sure that the thread responses (the questions) don’t violate any community and instance rules?

I may be overthinking it, but such a huge event would involve a lot of coordination from many different people.
