Quick question 

I edited the Maracana stadium article that incorrectly stated it was the largest in the world.  I was planning to go back and do further editing when I noticed you reverted it without comment.  It was never the largest stadium in the world, this is inaccurate.  I made an edit that was both (IMO) well written and unobtrusive.  Please advise me on why you reverted in and how it can be corrected.
