 * Hi,
 * there is a bug:
 * > Notice: Undefined variable: comment_tag in …/wp-content/plugins/last-updated-
   > shortcode/last-updated-shortcode.php on line 59
 * It seems You are missing the **global** keyword in front of the variable, it 
   should be like this:
    `global $comment_tag;`

 * I have got a suggestion: Could you please make it HTML5 ready? That would mean
   the output of the shortcode would result in this:
 *     ```
       <time datetime="2009-10-22T13:59:47-04:00" pubdate="pubdate">
         October 22, 2009 1:59pm EDT
       </time>
       ```
   
 * The “pubdate” should be optional (not in default shortcode). The non-HTML5 compliant
   browsers would still render it normally, ignoring the unknown time tag.
