Make sure you close all of your HTML Comments from here on out. Especially don't forget to close 'em when you start and end your Javascript or CSS.
The new IE Security Update will totally bungle your site if you have an opening comment that is never closed. I just got to discover that when a friend called me in a panic because "My site is totally gone!"
She hadn't closed a comment in the CSS styles at the head of her page, so every page on her site displayed totally blank, even though the source code was there. Should have always been this way probably, but even Netscape overlooks that one these days.
Now you know where to look first if someone with the new XP/IE security update (I got it yesterday, others got it today apparently) can't see your site. Or if you don't use IE, you might want to fire it up at least long enough to make sure your sites are still showing as intended.
It's an easy one to miss!
