The state of this plugin

Sorry to hear that..

Wondering if the steps in this article wouldn’t be a better alternative to a plugin..

I spend a good amount of time working in WordPress environments. Seems like every theme comes with jQuery and the all use the local copy, obviously that is not a great idea, luckly there is a simple way to correct this oversight with just 6 lines of code.
Add to the end of your wordpress theme directory/Functions.php file

function jquery_cdn() {
   if (!is_admin()) {
      wp_deregister_script('jquery');
      wp_register_script('jquery', 'https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js', false, '1.7.2');
      wp_enqueue_script('jquery');
      }
   }
add_action('init', 'jquery_cdn');
