title: Serve jQuery UI from Google's CDN or as a local copy?
body: <p>while it's better to serve jQuery from Google's CDN jQuery UI is a different beast. My local modified copy weighs 60kb and the one in Google's CDN ~200kb.</p>
  
  <ul>
  <li>Are there any numbers on how many sites uses the CDN? (read: how many users have it in their cache). How do I know/calculate if it's better to serve it locally?</li>
  </ul>
