It's a whole lot worse in FF3b4/Win. Also you have 2 hosting issues. CSS and the maing BG image timed out on me (about 3 mintues before I posted this). Your deep-linking of the W3C image cost your load time over 15 seconds ("waiting for www.w3.org..."). So as it stands the site is muck, but once you sort it out, I can kinda see that it might be OK (but the text, even with it's black background, is going to be hard to read against that background image, I fear)
