Today’s Boston Globe has a web design comparison between the Bush and Obama versions of whitehouse.gov. The article is very informative for those of us working in visual design and for those who are thinking about designing their own web site. I’m including a link to the article here. And, I’d like to add my own 2 cents.
Layout
The Bush layout for whitehouse.gov used a typical three column layout underneath a horizontal banner.

The Obama layout has a large top section divided into two distinct areas over a three column layout. Obama’s designer knows about Fibonacci based proportions which we see here as 1:2:3.

The result is a much more visually appealing layout because the eye tends to prefer proportion to symmetry.
