The rule about changing article titles came down from Jimrob in his latest rant, the one that gets posted to breaking news at least once a week.
The rule about "editing" titles make it clear that it's "along the lines" of "doing a search on a significant word" from the "title of your article to reduce the number of duplicates".
In this case, I added significant search words relevent to the subject onto a headline that was otherwise vague.
Now, run tell that!
