title: Biggest GWT Pitfalls?
body: <p>I'm at the beginning/middle of a project that we chose to implement using GWT. Has anyone encountered any major pitfalls in using GWT (and GWT-EXT) that were unable to be overcome? How about from a performance perspective?</p>
  
  <p>A couple things that we've seen/heard already include:</p>
  
  <ul>
  <li>Google not being able to index content</li>
  <li>CSS and styling in general seems to be a bit flaky</li>
  </ul>
  
  <p>Looking for any additional feedback on these items as well. Thanks!</p>
