Live audience.
Two debaters, one adjudicator. Fact checkers - facts are checked live,
results/photos/etc., are shown on screen. Crowd helps judge who's
right (but adjudicator has final say). Fact checks can come back
"unclear".
Point scoring system. Overtalking, shouting, being a douche, lying,
etc. are penalized. Being right or funny is rewarded.
System for audience questions/challenge. Need to manage volume/
quality. Maybe audience members have to come on stage to talk? And
give their name.
Full disclosure caveats are required.
Audience can tweet to adjudicator and fact checkers. And to debaters?
