I like the word, I just don't like the fiddliness.
Try saying the word "THAC0" out loud to a group of non-gamers, while keeping a straight face. Then try to explain to them what it means.
You are all missing the main problem with THAC0. Pronouncing it. Most people pronounce it as thack-oh, when I think it should be pronounced thay-coh. This confusion and discrepancy is really what makes THAC0 evil (see, you pronounced it incorrectly in your head as you were reading this!).
We switched pretty quickly to pronouncing it "Thwack-Oh" because it was more fun."Thayk-zero" would be more accurate, I think.
