In the words of the judges on a TV show I've been watching, So You Think You Can Dance,
"Yeaaaaaahh!!! YEAAAAHHH!!! WOOOOOO!!! That's competition!! That's what I'm talking about, YEAH!!"
Now if only Microsoft could comprehend the philosophy, they would stop making excuses for their corporate partners and start asking them to simply make their web sites compliant.
Oh, but oops, that would break their sites on IE... *sigh* .. Oh wait .. Ahh, got it .. they did understand it, they've been telling their customers to retain broken code that only works on IE and not to make it standards-compliant so that it keeps working on IE .. maybe they're not so stupid. Improper? Yes. Stupid? No.
