"Trends" in law department management

Why is it that journalists fixate on "trends?" I speak with about one every two weeks, and they want to know that some one-off effort, like offshoring, is a trend. To me that term means more and more law departments are following the idea, so how can two examples make a trend? The journalists exaggerate a ground swell when it is really an example of "one swallow does not a Spring make." I am cautious about generalizing on anything regarding law departments.  Perhaps this blog will erode some of my cautiousness.
