The importance of human-readable markup. Via Slashdot, a new HTML rendering bug that can crash Internet Explorer, Outlook, and other products that use Microsoft HTML rendering libraries.
Thats not terribly funny. But heres the funny part. Heres the markup that makes it crash:
<html>
<form>
<input type crash>
</form>
</html>
Presumably there are other variations, but that just made my day. [dive into mark]
