I apologize for any misunderstanding in the question.
They're not any better for the game than any other 50/50 method, I just find them interesting because they were well done. I'm not crazy about "We asked 100 housewives, have you ever had more than one leftover casserole at a time," but when you ask 100 Catholic priests if they believe that miracles happen, and you get an answer of 99, that's something to talk about.
Some guy put out a Mac Card Sharks game back when I owned and could use a Mac. And by golly, there were some interesting questions to it. If "Card Sharks" had done all EG questions from the start, I'd have no problem with it. It seemed like the CBS version thought "We're coming back, bigger and better and so on, and now we have TWO new question types! TWO!" as opposed to "The game show you barely had a chance to miss is coming back, just on a different network.
I'm certainly not against that type of question; I thought it was used very well as the opening question for Greed, and It Takes Two, and when the questions are interesting, that's great. I didn't think that many of the EG questions on Card Sharks were interesting, and certainly not something I'd remember after the fact.
