For good web design, I have chosen Facebook.
I know it might not seem like a good choice for “good web design” but something that I think is more important than anything on the web is user friendly interfaces. I think that facebook comes second only to google when it comes to user friendly-ness. The controls are simple, buttons lead to where they are supposed to and the user interface of your own personal profile is almost 100% customizable. It’s as easy as dragging and dropping the different sections into the place where you want it to go. If it’s not supposed to go there, it snapps back to it’s original position. If you don’t load it up with all kinds of ridiculous third party add-on’s, it’s simplicity at it’s best… which is important on a social networking site with so many users.
