I'm really against the second-screen space. I feel like it's this weird industry where broadcasters, who have checks to spend, want this tech that users tend to avoid. Users like interacting in the places where they already interact, with the people they already know. Getting them to buy-in to a specific place to interact isn't that compelling.<p>Maybe try a gameshow via iPad, and you might have something pretty compelling. 1 vs 100 would actually be pretty amazing if you could pull off the backend video infrastructure needed.<p>And why not make it 1 vs 1,000,000... and have each member of the mob be worth $1.
