In WordPress the “look n’ feel” is called Themes. There are 1.000+ different designs to choose from. Most of them can be altered in the code, the style sheet and plugins.
The challenge is to find one you like and that it works in different browsers. For instance I can’t get the navigation tabs to work in This Just In! in Internet Explorer 6 and 7. In other themes the so called lightbox doesn’t work proparly, and so on.
I like to have a “clean” design that works so I guess I have to keep looking. Don’t be surprised if the design keep on changing…
