I think that's the prettiest page I've ever seen on their network. Hopefully we'll see some creative/design refreshes this year -- it makes a big difference.
If you look at some of the newer sites, they're generally prettier than the original trilogy sites. Still have the same basic design and still all about the text of questions and answers.
I love the simple design of the main sites - SO, SU and SF. Keeps the question and the answers as the central focus. Things don't have to be pretty just for the sake of it.
