I think Ed’s Cecil. For one thing, I doubt the claim that “Cecil Adams” has never been photographed. Even if you don’t have a car (which Cecil admits owning), you get your photo taken every time you get money from the ATM. That had me thinking that “Cecil Adams” is a pseudonym for somebody else.
Another clue that points to Ed is the fact that Cecil never appears on his radio show. Why? Maybe because Ed Zotti is also on the show and the two can’t appear in the same place? We all know that Ed Zotti was not “Cecil”'s first editor, but that doesn’t mean he isn’t Cecil. It might just mean he decided to edit his own column under his own name. Zotti has written a book for kids called “Know It All” which not only gives a kids-friendly version of the Straight Dope, but also explains how to research unusual questions–something “Cecil” has to do every day.
One more thing, when I read the introduction to Triumph of the Straight Dope, I thought I recognized the style and assumed it was Cecil writing–until I came to the end and saw the name “Ed Zotti.”
