This was something I was going to say, too. Don't get me wrong, US geography and culture is interesting, but that was really US-centric. Really US-centric. I can understand why TV and entertainment are US-centric, and believe that it makes sense for those two to be as US-centric as possible. I can also understand why the geography was very US-centric: when you're going for a large target audience, you want to aim for it to be relevant to people.
But there seemed to be countless US politics questions - there's the entire history of the world to focus on, and tons of art and culture that also is categorised under history, not just one country's government. I stopped clicking on history after I got two rounds of five US politics questions that no-one outside of America has a hope in hell of answering.
And Sports - maybe I'm doing that ignorant British thing again, but there's an entire world of sport. Football (soccer) is the most popular sport in the world, and yet there was not one question about it. Nothing about other big sports, like tennis or golf, or even general sports questions, like "How many players on a hockey team?" or "In which sport would you find a 'Wing Attack'?". There wasn't even anything about the Olympics.
I appreciate that, as Sporcle Live is aimed at the USA, the USA will be the main audience, but with such a US-centric question base, you run the risk of alienating the rest of the world, where eventually you will be looking to expand.
