- the word "centroid"**
* I wanted some clever pun for the title, but everything I came up with—"Staying Centroid", "The Centroid Less Traveled", etc.—just seemed hopelessly lame (or entirely nonsensical). So there you have it. "Centroid". That's the post-title. (Well, actually, "Centroid*". Ooh, meta!) Love it or leave it.
** Loosely/metaphorically speaking, the center of balance or gravity (though you can go here if you really want the full geek-o-logical breakdown).
