[Originally posted on The Farm. I thought this might be of more general interest since it's about design.]

The web application frameworks Rails, Django and Symfony not only have the same general approach to their frameworks, they also have the same general look on the banners of their webpages. These frameworks all follow the what The Pragmatic Programmer called the DRY -- Don't Repeat Yourself -- principle, but that principle doesn't rule out repeating others!
