What Makes a Good Web Design?

Grand Master Math asks: "I'm currently redesigning my website and I have checked out tons of various web sites, gone from link to link, etc...to find the best web design techniques, layouts, and features. Wow Web Designs proved to be a pretty useful site, as it showcased virtually 'the best of the web' in design and creativity. I was wondering what the Slashdot community has to say about web design and what the best web design should implement and address. From browser compatibility, to simplicity and complexity, and customization to user interaction, what should a perfect web design incorporate?"
