ESPN's browser-upgrade page is a good example of how even the kind of sites that held onto Netscape 4 support well into the current millenium are finally not only embracing web standards (or, rather, hiring standards-using designers and letting them do their damn jobs) but also explaining their use of standards to the general public. Notice that they do not just say "upgrade because newer is better" the way web sites used to when they went from "3.0" to "4.0" browser support way back when.
