So, Mr. Gates, you say you believe in interoperability. Then why, pray tell, doesn't the web page of your interoperability communiqué conform to the HTML4 standard as it claims to? Why does the W3C validator diagnose 126 errors on your page?
You say you believe in interoperability. Then why is your document served in different versions to different browsers? Why does your server sniff out the Opera browser and send it different style sheets from the ones you send to Microsoft's own Internet Explorer (WinIE)? As a result, Opera renders the page differently.
