Awesome. One Microsoft team heard my pleas for clean XHTML. By the way, the new Word 2007 has the ability to post to blogs built in. Joe Friend has been writing about it.
Lots of Microsoft program managers push back and say "normal people don't care about HTML quality."
That might be true (although we all hate it when our pages don't display right on all browsers, or when they are slow to load) but the influentials who write reviews and tell their friends (or set up their computers) do care about such things.
One guy told me "but we have 10s of millions of users already, so why should we care?"
Well, you woulda had 10,000,001 if you had clean HTML.
