The Center of Things

I'm unequivocal about this: Centered things (think Alice on the Brady Bunch grid) are better than left- or right-flushed things. On my neighborhood stroll this evening, I happened to notice for the first time--I'm not the most observant person I know--a row of houses with doors that have centrally placed knobs, not knockers (those are almost always centered), but knobs! How cool is that? There's an architectural backstory somewhere...
