Hmm, so one link out of a ton on this page isn't set up correctly and that merits an "epic fail"? You're a little too harsh don't you think? The funny thing is that if you had actually looked at the code, you would've seen this:

<code><a href="http://developer.yahoo.com/yui/" rel="nofollow">Yahoo UI Docs</a></code>

The space in front of the "a" is what actually caused that, not a missing closing tag. You should really ease up on the cliche phrases like "epic fail" and simply consider just nicely helping out these quirks instead. Regardless, thanks for catching that. Fixed.
