title: Is referencing jQuery from ajax.googleapis.com bad practice?
body: <p>I've seen it recommended to reference jQuery via:</p>
  
  <pre><code>&lt;script type="text/javascript" 
      src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"&gt;
  &lt;/script&gt;
  </code></pre>
  
  <p>The idea being most people already have a cached copy on their client.</p>
  
  <p>What if a hacker replaces that file on google's server? They could do an infinite number of "evil" things from $(document).ready().</p>
  
  <p>Am I paranoid or is this bad practice?</p>
  
  <p>Edit:
  Obviously this is a matter of opinion. But I think the best answer is ceejayoz comment</p>
