I don't really care when someone edits my answers, but it grinds my gears when someone sloppily edits my answers.
So, why was this edit approved?
First, you never put a city's name in quotes. Second, it really is the "Sears Tower", not the "Sear's Tower". Lastly, almost every other edit wasn't an edit at all, but a re-typing of my exact words.
The only edit that might seem legit is putting the movie's name in italics, but that shouldn't have passed the "insignificant edit" rejection reason.
