Web Dev with IE
Everybody who has done any cross-browser web development is aware of the many quirks of IE6, so it is good to read, as Scott points out, that the IE team is addressing many of them with IE7. While it isn't 100% yet, I've noticed that more often than not, if you get it right in Firefox, it looks right in IE7 and vice-versa. That certainly cannot be said of IE6.
And on that note, I'd like to draw more attention to the IE web developer toolbar, which is mentioned in the IE team's blog. Those who use Aardvark in Mozilla should definitely give this add-in a whirl. It's not the same, but it does offer many similar features and some that Aardvark doesn't. It helps take the guesswork out of troubleshooting layout and styling issues.
