Lol! I was waiting for someone here to link to that. While it's good you read things outside this forum, you need to understand the data. IE9 leads in HTML5 support? Not likely. And IE9 is not good at very much. It's the worst browser on the planet.
Wired the most objective blog on world ? I don't really care, I'm not a stupid fan (I'm running Safari) or a stupid hater. I'm not a kid anymore, you probably don't understand but for us (professional) it's a huge step forward. http://www.engadget.com/2010/11/02/w3c-tests-html5-browser-compatibility-crowns-ie9-the-champ/
Then you'll love this. While IE9 is a huge step from IE8, it's a huge step below the same support and compliance every other browser has today, and IE9 still won't be out for another six months.
