@Kazaxat - I believe everybody that creates anything hates to be edited. There have certainly been occasions when Sporcle HQ has edited some of my quizzes in unsatisfying ways. Removing least guessed answers is common. Most (possibly all) editors, in my experience, do not make substantive changes to a quiz, such as removing lines of data, replacing lines of data with different data or replacing images. Speaking for myself, as a new editor, I always try to contact a quizmaster about making any changes to a quiz. There has been one occasion when a quizmaster never got back to me. Because I wanted to EP that quiz, I decided to edit it quite a bit myself. If I see a quiz that has an obvious typo or misspelling here or there, I usually fix those right away without comment or contact. "Can you name the name the TV show ..." I'll delete the extra "name the". I'll change Amy Poeler to Amy Poehler.
In your original quiz I would have gotten 8 correct answers. In the new version I got 8 correct. I would have gotten Feivel (if I spelled it correctly). In the new version I was able to replace that correct answer with Rocky. Hmmm, is that Danger Mouse in the original? I would have gotten that correct. Ergo the original version was better! Wait ... Danger Mouse is also in the new version!!! I just didn't see the little DM logo so easily and missed it. Rats! Thus either version is just as good as the other.
I guess I just woke up and felt like writing :) Collaboration is a great component in the creation process. When a quiz is finally published, it has always been a collaborative effort along the way. In an extreme example - You create a quiz. You launch it. The quiz gets positive comments and high ratings. The quiz is EPed. The quiz is praised in the comment section. The quiz is published completely intact.
However, most quizzes can usually be improved before they are published. It's hard to judge your own baby with a critical eye. Feedback is invaluable and should be treasured. There are concerns that HQ might have that are unknown to you and me and that cause them to alter a quiz. I like the Map you created for your original quiz. It's beautiful work, but perhaps it's far far easier for HQ to alter a picture box quiz at a future date if Walt Disney calls them on the phone and says, "Please take Mickey out of that quiz." Who knows? Not me.
In summary - in my opinion the new version of your quiz is no better or worse than the original in quality or content.
One day soon this entire Google Group will be frozen in time. "I'll see you on the other side, brother."
