Web Design Practices is all about helping the design make informed decisions about web design. Have questions on breadcrumbs? What about link colors and treatments? Think that your current implementation of searching is WAY off base? Take a look here and see how others are doing it.
I particularly love location of search as plotted out on an 800x600 pixel grid. It's excellent.
This is a great site that is well laid out, easy to navigate and easy to read. A great tool for any designer.
