Well, I reckon no place IS guaranteed of foolproof editing.
Look what yourDict. has in their opening paragraph: Best & Worse Corporate Name Changes I didn't at first assume it was an error, but when I checked down the page, sure enough the heading reads: Best & Worst Corporate Name Changes.

Anyway--I strongly disagree with using the term ground zero to refer to the site of the WTC, as well as with saying the WTC was bombed. It was not bombed--it was hit with airplanes. It doesn't matter that the planes had the effect of a bomb--an airplane is not a bomb, and therefore by extension, using the term ground zero is inappropriate.
