Looks like IE is keeping track of this now. Compatibility tables for every major version of IE, dating back to 5.

Bringing CSS3 selectors to IE. Includes compound classes.

Not fixed in iOS5. Boo!

JAWS currently mis-ranking HTML5-style heading algorithm. A quick tweak involving ARIA fixes it.

Looks like IE8 is collapsing images with max-width in some circumstances. Gross. http://jsbin.com/imuni6/edit#preview

An installable plugin for IE that adds support for WebGL

More slightly depressing news around conditional comments and compatibility mode: the button will continue to show if you set IE=edge while using conditional comment HTML classes.

@necolas puts together a list of IE6/7 prefix hacks, plus a formulation that works as a faux media query for IE.

The state of media queries in Windows Mobile 7: nonexistent. At least we can use conditional comments to patch it up.

An attempting-to-be-definitive collection of HTML5 functionality shims.

Labels wrapping form elements aren't clickable in iOS

Good advice on filing good bugs with browser vendors.

Nice.

Fiendishly clever.

IE javascript memory leak detector. Originally written and released by MS, they discontinued support, but under its BSD license it has been hosted and maintained elsewhere.

Something I noticed.. if an mp3 file in an <audio> tag is too short (<0.2s), it won't play. Solution: http://cl.ly/3oFn

Small (really small!) Javascript that appends a class for the user agent.

IE7 indents the whole inline-block box, meaning your replacement disappears. `text-indent: 0; font-size: 0; line-height: 0;` causes the text to be invisible in IE7, meaning you don't need an indent. Using the `zoom:1;display:inline` hack also seems to fix the issue.

$##*$%#$*$%*!!!!!!!

IE has issues with InnerHTML and HTML5. This should solve it.

Test case and fix

Replaces Trident with the Webkit rendering engine in IE. This is not a hack, it uses IE-provided API's in a completely kosher (if unintended) way.

If the immediate parent of *some* form elements hasLayout and it's immediate ancestor has margin, the form element inherits the sum total of all the margins of all the ancestors. Consider my mind blown.
