title: Use Google Analytics custom events for feedback form
body: <p>I was thinking of having a simple feedback form in my website. 
  It would be something like: </p>
  
  <pre><code>Your Feedback will help us improve.
  [                                ]
  </code></pre>
  
  <p>and then a textfield/textarea where the user can type (let's say) up to 100 characters of feedback. </p>
  
  <p>Rather than handling it all myself on the server-side I was thinking to use Google Analytics (since my site is already wireup) and every time a user writes a comment, send a custom event to google analytics.</p>
  
  <p>I think it might work.</p>
  
  <p>Can people suggest a better approach or point out any problem with this idea?</p>
