So this is really great, and for a while I've been thinking about what a stock market game for pop culture would be like. It'd serve as a great discovery tool, like searching for that penny-stock that's going to blow up, and it'd be a great way for fans and haters of particular celebrities to duke it out in the market place (think of the 50 Cent / Kanye competition, or the rabid fans of Chris Brown and those who detest him). You could gather information from across a whole host of resources (imdb, movie ticket / record sales, tabloid sites, twitter, spotify plays) to come up with predicted performance forecasts for each celebrity. Something like that would make people feel they played a direct part in a particular success story. Early "investors" would be considered more loyal fans, you could incentivize using concert tickets and schwag, etc, etc - there are lots of ways to 'gamify' it.
