Yesterday, when I was writing about using personas in professional service marketing, I was reminded of a “rule” that I either picked up when studying interactive design or was reinforced for me during that time. The rule is include enough (design, features, etc.) to accomplish the job but no more.

I’m often reminded of this rule when people ask “how long should a blog post be?” or “what is the right length for my newsletters?”. My pat answer has always been, pick one point, write enough to make your point and no more.

And another thing… just kidding ; )
