    Display a post specific list of tags,extending this from an example bhlarsen posted on get_tags(). There is probably a better way to do this.

    $tags = wp_get_post_tags($post->ID); //this is the adjustment, all the rest is bhlarsen
$html = '<div class="post_tags">';
foreach ( $tags as $tag ) {
$tag_link = get_tag_link( $tag->term_id );

$html .= "<a href='{$tag_link}' title='{$tag->name} Tag' class='{$tag->slug}'>";
$html .= "{$tag->name}</a> ";
}
$html .= '</div>';
echo $html;
