What happens if you strip out all java scripting?
when i test your page, my javascript error console shows a number of problems:
ubuntu-light-webfont.woff:-1Resource interpreted as Font but transferred with MIME type text/plain.

viewing source of your page, it looks like you are using a number of HTML 5 techniques, but you use the XHTML doctype:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
