I was, yes. I saw your post after posting my own, and thus replied to you.

My thought is that the flavor of yogurt grows on you, more easily so if you either start young (the girls) or if you already like sour cream.

I most definitely prefer a *thick* authentic yogurt. Many of the yogurts most typically eaten in America are rather thin and runny. If you have an opportunity to try one that is imported from Greece or the Middle East (I'm told Trader Joe and Whole Foods has one, as do speciality stores) you might find that the thicker consistency makes a more appetizing base for a sauce, appearance wise.
