I met D at the Unofficial Portland Post-NaNoWriMo January Gathering, and we were talking about our respective novels (de rigueur when meeting another NaNo participant), and as I was mentioning that I wrote the advice column, he said "Oh! You're Dr. Eldritch!" That was SO COOL! I was recognized! I almost gave him an autograph. Point is, if I got a kick out of just that, I bet published novelists get quite a rush when people first say "Oh, you're the one who wrote that book!"
