    </template>
    <script>
        Polymer({
            ready: function(){
                console.log('html: '+this.$.content.innerHTML);

Unfortunately, the implementation inserts content nodes as siblings of content, not as nested nodes. That said, after everything is ready, the structure of document would look like:

<content id='content'></content>
content I am trying to access

not as you probably were expecting:

<!-- THAT IS NOT HOW IT’S COMPOSED -->
<content id='content'>content I am trying to access</content>

Fortunately, you are still having an access to childNodes within template context:

  Polymer({
      domReady: function() {
        var content = '';
        this.childNodes.array().forEach( function(el) {
          content += el.textContent; // do whatever you want here
        });
        console.log(content);
      }
  });

  //⇒ content I am trying to access

Hope it helps.
