Can I give this a double ++? For a while I have felt that site developers should be more aggressive in moving towards current standards (like XHTML, CSS . . .) So someone with Navigator 3.0 or IE 2.0 can see the site? Tough cookies. There is the "web standards project" (or something like that, sorry, no link at present) that is suggesting people have their markup to tell people with broken browsers (including Netscape 4.7 and lower) that they need to update their browser.
I am running IE5.5 here, and the pink and blue themes would not display. The blue theme looked great.
