IE8 now renders the “Acid2 Face” correctly in IE8 standards mode.
The W3C Cannot Save Us
To get a better future, not only do we need a return to “the browser wars”, we need to applaud and use the hell out of “non-standard” features until such time as there’s a standard to cover equivalent functionality. Non-standard features are the future, and suggesting that they are somehow “bad” is to work against your own self-interest.
Indenting your code
In HTML whitespace is not treated as significant, and therefore it gets collapsed. This is a problem when you want to publish code because your indenting will disappear. The most common way around this is to wrap code in a pre element, but that looks like crap because it's always the default monospace font, and you can't style it. A better way is to use CSS, specifically white-space: pre;.
In WordPress, log in to the admin section, click Presentation and select Theme Editor. Choose Stylesheet from the list on the right, then look for the code declaration. Add white-space: pre; and you're done. Now, whenever you want to display code, wrap it in a code element.
