Half-full or Half-empty?

Front page headline from the Washington Post (Fri. Feb. 27):

Iraqi Cleric Yields on Elections: Agrees to Delay of Six Months

Front page headline from the New York Times (same day):

Iraqi Ayatollah Insists on Vote by End of Year

The Wash. Post headline is more accurate because it is the change in position that is the news but in the end it may be the NYTimes headline which proves more important.
