title: Get product's tags on category page in Magento?
body: <p>How can I get and display product's tags on category view (in loop where products are listing)? 
  I used code (from <a href="https://stackoverflow.com/questions/2053776/how-to-display-tags-product-in-view-phtml-of-magento">another question</a>) and put in \app\design\frontend\...\template\catalog\product\list.phtml:</p>
  
  <pre><code>&lt;?php $_tags = new Mage_Tag_Block_Product_List(); ?&gt;
  </code></pre>
  
  <p>and in foreach (where products listing) display tags:</p>
  
  <pre><code>&lt;?php if($_tags) : ?&gt;
      &lt;?php foreach($_tags-&gt;getTags() as $tag):?&gt;
          &lt;span class="tag"&gt;&lt;?=$tag-&gt;getName()?&gt;&lt;/span&gt;
      &lt;?php endforeach; ?&gt;
  &lt;?php endif; ?&gt;
  </code></pre>
  
  <p>And it isn't working, because instantiating $_tags is giving me error: </p>
