For performance consider moving these script tags to a block the end of the body

```html
<body>
...
{% block base_scripts %}
  <script src="http://documentcloud.github.com/underscore/underscore-min.js"></script>
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>
{% endblock base_scripts %}
</body>
