Title: Double loading of jQuery

I noticed a little flaw in the header.php file (and also in Iubenda blog): jQuery is loaded twice. First time is loaded version 1.5.2 with the script tag I removed, the second time is loaded automatically by WP.
Not a serious problem, but increases the page load time a little.

Also I suggest you use in your own blogs the plugin Use Google Libraries (http://jasonpenney.net/wordpress-plugins/use-google-libraries/) that changes WP behaviour and uses jQuery minified from Google servers (hopefully already cached 'cause it's used by many websites).
