I see the theme of the perl6.org site to be in the direction of Thing Explainer -- that is, to be as inclusive as possible, without compromising too deeply into the quality of the design and implementation.

People go there (and here) with many languages, backgrounds, experience, levels of sophistication, and a finite bucket of RoundTuits. It's a compromise between making a few mono-browed grunting hackers grumble (who frankly don't need the hand-holding), versus putting on a friendlier face and getting new visitors to stay 5 minutes longer, and increase the chances of joining the community.

But if you want, I can dig out the CSS to change the butterfly to your favorite Bruce Campbell chainsaw-as-a-prosthetic movie poster. I'm sure that will be parent-approved across the world.
