Change Is Hard for the Post

The Washington Post recently changed their weekend format, doing away with their separate Book World, moving some reviews into their weekend opinion Outlook, etc. This weekend they had a glitch, which I failed to notice yesterday, but which was evident today. Briefly put, they printed their Sunday editorials, letters to the editor, and op-eds on Saturday, and then again today. I assume both sets of pages were in the computer and the wrong one got included in the press run. Such is the nature of change and computers.
