Get IE 8 to behave like 7

Believe it or not, IE7 works better for much of what I'm doing; IE8 hasn't made things better at all. To get IE8 (or the upcoming 9) to behave like 7, use the following line in the head tag:

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />

Of course, 9 will add a ton of HTML5 and CSS3 features and is worth exploring and then making a judgment on it merits.
