Most of us on the forum are smart when it comes to game shows, because we're around so many others who already know this information: people in the biz, former contestants, even future contestants who've done their homework. So for most of us, the article isn't really anything we haven't heard before. The only thing that was news to me was the up-to-10-hour wait on Wheel. (Guess I should bring the DS.)
However, I get the feeling that this was written for more casual fans of the genre. Even someone with a modicum of common sense could probably figure out that game show winnings are taxed like any other sort of income, but I would bet that very few people outside the loop realize (for instance) just how rigorously contestants are screened, or what exactly The Powers That Be™ are looking for in a contestant. I know in the course of my auditioning for Wheel, I saw many people who clearly didn't know what they were in for, but I also saw many people who seemed like they were just right on top of it.
