It was once famously said

“Prettiness, that’s what’s important. Followed by Navigation then content.”

… OK maybe not that famous but it was said, and it was in response to the question: Which is more important content or navigation? The response in it’s own right has it’s points. People will argue that a site like Google isn’t very pretty, nor is Amazon. What they do offer is function and service, but I would actually argue that Google is full of “prettiness”. Google may not be pretty everyday but she certainly does like to dress up every now and than as seen on the Holiday Logos archive, and there is something else, Google has a certain kind of symmetry.
