Fancy article tag formatting. Expects "field_tags" to exist and a term reference field.

node.tpl.php

<?php
// Voila! $submitted now has date and tags.
?>
<p class="submitted"><?php print $submitted; ?></p>

template.php

<?php
function glamanate_preprocess_node(&$variables) {
  $node = $variables['node'];

  $date = format_date($variables['created'], 'published');

  $variables['submitted'] = t('@date', array('@date' => $date, '!author' => $variables['name']));

  //Find out the tags
  if (isset($node->field_tags) && $variables['page']) {
    $article_field_tags = field_get_items('node', $node, 'field_tags');
    $article_tags = array();
    if(!empty($article_field_tags)) {
      foreach($article_field_tags as $tag) {
        $tag_link = t('<a href="@url" title="View articles about @tag">@tag</a>',
          array('@url' => url('taxonomy/term/'.$tag['tid'], array('absolute' => true)), '@tag' => $tag['taxonomy_term']->name));
        $article_tags[] = $tag_link;
      }
      $article_tags_inline =implode(', ', $article_tags);
      $variables['submitted'] .= " | tags: " . $article_tags_inline;
    }
  }
}
