Here's a comment on my blog entry about tightening copy.
It's funny, tom, but I've gone through the same thing a few times, at least from the copy editing side. In my case, I've gotten a story for third (final) edition and have edited it. Then I had to move copy around a bit or enlarge a photo to make it fit. We were using pagination (this was the 1990s), and I was doing the editing and paginating, so fitting the story in wasn't a major problem.
Thanks for the comment.
