This sort of thing is never a good sign:
Code:
<!--[if IE 6]>
<link rel="stylesheet" type="text/css" media="all" href="http://comienzo.curtisdev.ca/wp-content/themes/Comienzo/assets/css/ie6-styles.css" />
<![endif]-->
<!--[if IE 7]>
<link rel="stylesheet" type="text/css" media="all" href="http://comienzo.curtisdev.ca/wp-content/themes/Comienzo/assets/css/ie7-styles.css" />
<![endif]-->
<!--[if IE 8]>
<link rel="stylesheet" type="text/css" media="all" href="http://comienzo.curtisdev.ca/wp-content/themes/Comienzo/assets/css/ie8-styles.css" />
<![endif]-->
The most you should ever need is an IE6 conditional comment and even then they're only needed in rare circumstances for things which simply aren't possible with IE6.
