title: Jekyll not listing posts
body: <p>I can't seem to get some very basic ruby to work within Jekyll. I have an ultra-simple loop to get my posts from inside /_posts :</p>
  
  <pre><code> &lt;ul&gt;
          {% for post in site.posts %}
              &lt;li&gt;
              &lt;a href="{{ post.url }}"&gt;
                  {{ post.title }}
              &lt;/a&gt;
              &lt;/li&gt;
          {% endfor %}
  &lt;/ul&gt;
  </code></pre>
  
  <p>The posts inside _posts are called</p>
  
  <pre><code>2013-03-16-how-i-do.md
  2012-01-01-hello-world.md
  </code></pre>
  
  <p>Inside _config.yml, I've set <code>permalink: pretty</code>.</p>
  
  <p>What's odd is that it doesn't seem to even iterate through that loop at all— if I add some text inside the loop, even before the li, it doesn't post show up at all.</p>
  
  <p>I'm currently using ruby-2.0.0-p0 — have there been any syntax changes that might be causing this?</p>
  
  <p>Thank you!</p>
