You can't use jQuery to dynamically set the title of your web page, even though the syntax (and the documentation) would lead you to believe that you could. I spent about an hour today tracking this one down, before coming across this gem.
Instead of saying:
$('title').html('My new page title');
document.tile = 'My new page title';
To really put a wrench in the whole matter, the jQuery call works in Firefox and Safari, but not in IE.
